The HE4056 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.When the input supply (wall adapter or USB supply) is removed the HE4056 automatically enters a low current state dropping the battery drain current to less than2μ A.The HE4056 can be put into shutdown mode reducing the supply current to 55μA.Other features include Battery temperature monitor, under-voltage lockout, automatic recharge and two status pins to indicate charge and charge termination.1.1A Lithium Ion Battery Linear Charger Pin Configuration1.1A Lithium Ion Battery Linear ChargerAbsolute Maximum Ratings1.1A Lithium Ion Battery Linear ChargerCaution: The absolute maximum ratings are rated values exceeding which the product could suffer physical damage. These values must therefore not be exceeded under any conditions.1.1A Lithium Ion Battery Linear ChargerNote: The ●denotes specifications which apply over the full operating temperature rang, otherwise specifications are at TA=25℃，VCC=5V，unless otherwise specified.Description of the PrincipleThe HE4056 is a complete CC/CV linear charger for single cell lithium-ion batteries. CC/CV to charger batter by internal MOSFET .It can deliver up to 1.1A of charge current .No blocking diode or external current sense resistor is required. HE4056 include two Open-Drain charge status Pins: Charge status indicator CHRG and battery failure status output STDBY.The internal thermal regulation circuit reduces the programmed charge current if the die temperature attempts to rise1.1A Lithium Ion Battery Linear Chargerabove a preset value of approximately 145℃. This feature protects the HE4056 from excessive temperature, and allows the user to push the limits of the power handling capability of a given circuit board without risk of damaging the HE4056 or the external components. Another benefit of adopting thermal regulation is that charge current can be set according to typical, not worst-case, ambient temperatures for a given application with the assurance that the charger will automatically reduce the current in worst-case conditions.The charge cycle begins when the voltage at the VCC pin rises above the UVLO level, a current set resistor is connected from the PROG pin to ground, and the CE pin is pulled above the chip enable threshold.The CHRG pin outputs a logic low to indicate that the charge cycle is on going. At the beginning of the charge cycle, if the battery voltage is below 2.9V, the charge is in precharge mode to bring the cell voltage up to a safe level for charging. The charger goes into the fast charge CC mode once the voltage on the BAT pin rises above 2.9 V. In CC mode, the charge current is set by RPROG. When the battery approaches the regulation voltage 4.2V, the charge current begins to decrease as the HE4056 enters the CV mode. When the current drops to charge termination threshold, the charge cycle is terminated, and CHRG pin assumes a high impedance state to indicate that the charge cycle is terminated and STDBY pin is pulled low.The charge termination threshold is 10% of the current in CC mode. To restart the charge cycle, remove the input voltage and reapply it, or momentarily force CE pin to 0V. The charge cycle can also be automatically restarted if the BAT pin voltage falls below the recharge threshold. The on-chip reference voltage, error amplifier and the resistor divider provide regulation voltage with 1% accuracy which can meet the requirement of lithium-ion and lithium polymer batteries. When the input voltage is not present, or input voltage is below VBAT, the charger goes into a sleep mode, dropping battery drain current to less than 3μA. This greatly reduces the current drain on the battery and increases the standby time. The charger can be shutdown by forcing the CE pin to GND.The charging profile is shown in the following figure:1.1A Lithium Ion Battery Linear ChargerThe charge current is programmed using a single resistor from the PROG pin to ground. The program resistor and the charge current are calculated using the following equations.BATPROG I R 1450; In application, according the charge current to determine RPROG ,the relation between RPROG and charge current can reference the following chart:Charge TerminationA charge cycle is terminated when the charge current falls to 1/10th the programmed value after the final float voltage is reached. This condition is detected by using an internal filtered comparator to monitor the PROG pin. When the PROG pin voltage falls below 100mV for longer than tTEMP (typically 1.8mS), Charging is terminated. The charge current is latched off and the HE4056 enters standby mode, where the input supply current drops to 55μA ( Note:C/10 termination is disabled in trickle charging and thermal limiting modes).When charging, transient loads on the BAT pin can cause the PROG pin to fall below 100mV for short periods of timebefore the DC charge current has dropped to 1/10th the programmed value. The 1.8mS filter time (tTEMP) on the termination comparator ensures that transient loads of this nature do not result in premature charge cycle termination. Once the average charge current drops below 1/10th the programmed value, the HE4056 terminated the charge cycle and ceases to provide any current through the BAT pin. In this state all loads on the BAT pin must be supplied by the battery. The HE4056 constantly monitors the BAT pin voltage in standby mode. If this voltage drops below the 4.10V recharge threshold (VRECHRG ),another charge cycle begins and current is once again supplied to the battery. To manually restart a charge cycle when in standby mode, the input voltage must be removed and reapplied or the charger must be shut down and restarted using the PROG pin. Figure 1 shows the state diagram of a typical charge cycle1.1A Lithium Ion Battery Linear ChargerThermal limiting1.1A Lithium Ion Battery Linear ChargerAn internal thermal feedback loop reduces the programmed charge current if the die temperature attempts to rise above a preset value of approximately 145℃ . The feature protects the HE4056 from excessive temperature and allows the user to push the limits of the power handling capability of a given circuit board without risk of damaging the HE4056. The charge current can be set according to typical (not worst-case) ambient temperature with the assurance that the charger will automatically reduce the current in worst-case conditions.To prevent the damage caused by the very high or very low temperature done to the battery pack, the HE4056 continuously senses battery pack temperature by measuring the voltage at TEMP pin determined by the voltage divider circuit and the battery ’s internal NTC thermistor as shown in Figure 1.The HE4056 compares the voltage at TEMP pin (VTEMP) against its internal VLOW and VHIGH thresholds to determine if charging is allowed. In HE4056, VLOW is fixed at (45%×Vcc), while VHIGH is fixed at (80%×Vcc). If VTEMP<VLOW or VTEMP>VHIGH , it indicates that the battery temperature is too high or too low and the charge cycle is suspended. When VTEMP is between VLOW and VHIGH , charge cycle resumes. The battery temperature sense function can be disabled by connecting TEMP pin to GND.Under Voltage lockout (UVLO)An internal under voltage lockout circuit monitors the input voltage and keeps the charger in shutdown mode until VCC rises above the under voltage lockout threshold . If the UVLO comparator is tripped, the charger will not come out of shutdown mode until VCC rises 140mV above the battery voltage.Auto restartOnce charge is been terminated, HE4056 immediately use a 1.8ms filter time （ tRECHARGE ）on the termination comparator to constant monitor the voltage on BAT pin. If this voltage drops below the 4.1V recharge threshold (about between 80% and 90% of VCC), another charge cycle begins. This ensured the battery maintained (or approach) to a charge full status andavoid the requirement of restarting the periodic charging cycle. In the recharge cycle, CHRG pin enters a pulled down status.Stability ConsiderationsIn CC mode, the PROG pin is in the feedback loop, not the battery. The CC mode stability is affected by the impedance at the PROG pin. With no additional capacitance on the PROG pin, the charger is stable with program resistor values as high as 20K. However, additional capacitance on this node reduces the maximum allowed program resistor. Therefore, if IPROG pin is loaded with a capacitance C, the following equation should be used to calculate the maximum resistance value for RPROG ： PROGPROGC R ⨯⨯≤51021πAs user, may think charge current is important, not instantaneous current. For example, to run a low current mode switch power which parallel connected with battery, the average current from BAT pin usually importance to instantaneous current. In this case, In order to measure average charge current or isolate capacitive load from IPROG pin, a simple RC filter can be used on PROG pin as shown in Figure 2. In order to ensure the stability add a 10K resistor between PROG pin and filter capacitor.1.1A Lithium Ion Battery Linear ChargerFig.2 Isolating with capacitive load on PROG PinPower DissipationThe conditions that cause the HE4056 to reduce charge current through thermal feedback can be approximated by considering the power dissipated in the IC. Nearly all of this power dissipation is generated by the internal MOSFET-this is calculated to be approximately:BAT BAT CC D I V V P ⨯-=)(The approximate ambient temperature at which the thermal feedback begins to protect the ICis:JA D A P C T θ⨯-︒=145;So:JABAT BAT CC A I V V C T θ⨯⨯--︒=)(145For example: The HE4056 with 5V supply voltage through programmable provides full limiting current 850mA to a charge lithium-ion battery with 3.85V voltage. If JA is 100℃/W ( reference to PCB layout considerations), When HE4056 begins to decrease the charge current, the ambient temperature about:CT A ︒=⨯⨯--=25.4710085.0)85.35(145HE4056 can work in the condition of the temperature is above 47.25℃, but the charge current will pull down to below 850mA. In a fixed ambient temperature, the charge current is calculated to be approximately :JABAT CC ABAT）V （V T C I θ⨯--=︒145Just as Description of the Principle part talks about so, the current on PROG pin will reduce in proportion to the reduced charge current through thermal feedback. In HE4056 design applications don ’t need to considerate the worst case of thermal condition, this point is importance, because if the junction temperature up to 145℃ ,HE4056 will auto reduce the power dissipation.Thermal ConsiderationsBecause of the small size of the thin SOP-8 or ESOP-8 package, it is important to use a good thermal PC board layout to maximize the available charge current. The PC board copper is the heat sink. The footprint copper pads should be as wide as possible and expand out to larger copper areas to spread and dissipate the heat to the surrounding ambient. Other heat sources on the board, not related to the charger, must also be considered when designing a PC board layout because they will affect overall temperature rise and the maximum charge current.VCC bypass capacitorMany types of capacitors can be used for input bypassing, however, caution must be exercised when using multilayer ceramic capacitors. Because of the self-resonant and high Q characteristics of some types of ceramic capacitors, high voltage transients can be generated under some start-up conditions, such as connecting the charger input to a live powerHE40561.1A Lithium Ion Battery Linear Chargersource. Adding a 1.5Ω resistor in series with a ceramic capacitor will minimize start-up voltage transients.Charging Current Soft StartHE4056 includes a soft start circuit which used to maximize to reduce the surge current in the begging of charge cycle. When restart a new charge cycle, the charging current ramps up from 0 to the full charging current within 20μs. In the start process it can maximize to reduce the action which caused by surge current load.Board Layout ConsiderationsRPROG at PROG pin should be as close to HE4056 as possible, also the parasitic capacitance at PROG pin should be kept as small as possible.The capacitance at VCC pin and BAT pin should be as close to HE4056 as possible.During charging, HE4056’s temperature may be high, the NTC thermistor should be placed far enough to HE4056 so that the thermistor can reflect the battery ’s temperature correctly.It is very important to use a good thermal PC board layout to maximize charging current. The thermal path for the heat generated by the IC is from the die to the copper lead frame through the package lead (especially the ground lead) to the PC board copper, the PC board copper is the heat sink. The footprint copper pads should be as wide as possible and expand out to larger copper areas to spread and dissipate the heat to the surrounding ambient. Feed through vias to inner or backside copper layers are also useful in improving the overall thermal performance of the charger. Other heat sources on the board, not related to the charger, must also be considered when designing a PC board layout because they will affect overall temperature rise and the maximum charge current.The ability to deliver maximum charge current under all conditions require that the exposed metal pad on the back side of the HE4056 package be soldered to the PC board ground. Failure to make the thermal contact between the exposed pad on the backside of the package and the copper board will result in larger thermal resistance.Add thermal regulation currentIt will effective to decrease the power dissipation through reduce the voltage of both ends of the inner MOSFET. In the thermal regulation, this action of transporting current to battery will raise. One of the measure is through an external component(as a resistor or diode) to consume some power dissipation.For example: The HE4056 with 5V supply voltage through programmable provides full limiting current 1000mA to a charge lithium-ion battery with 3.8V voltage. If JA is 120℃/W, so that at 25℃ ambient temperature, the charge current is calculated to be approximately :JABAT CC BAT CC BAT）V R I V CC I θ⨯-⨯--=︒︒(25145In order to increase the thermal regulation charge current, can decrease the power dissipation of the IC through reducing the voltage (as show fig.3) of both two ends of the resistor which connecting in series with a 5V AC adapter.With square equation to calculate I BAT ：CCJAA CC BAT CC BAT CC BAT R T C R V V V V I 2)145(4)(2θ-︒⨯----=If RCC=0.25Ω, VCC=5V, VBAT=3.75V, TA=25℃ and JA =120℃/W, we can calculate the thermal regulation charge current: IBAT ＝1080mA. It means that in this structure it can output 1000mA full limiting charge current at more high ambient temperature environment.Although it can transport more energy and reduce the charge time in this application, but actually spread charge time, if1.1A Lithium Ion Battery Linear ChargerHE4056 stay in under-voltage state, when VCC becomes too low in voltage mode. Fig.4 shows how the voltage reduced with increase RCC value in this circuit. This technique will act the best function when in order to maintain the minimize thedimension of the components and avoid voltage decreased to minimize RCC .USB and Wall Adapter PowerHE4056 allows charging from a USB port, a wall adapter can also be used to charge Li-Ion/Li-polymer batteries. Figure 5 shows an example of how to combine wall adapter and USB power inputs. A P-channel MOSFET, Q1, is used to prevent back conducting into the USB port when a wall adapter is present and Schottky diode, D1, is used to prevent USB power loss through the 1K Ω pull-down resistor.Generally, AC adaptor is able to provide bigger much current than the value of specific current limiting which is 500mA for USB port. So can rise charge current to 600mA with using a N-MOSFET (Q1) and an additional set resistor value as highas 10K.HE40561.1A Lithium Ion Battery Linear ChargerHE4056 has two open-drain status indicator output CHRG and STDBY .CHRG is pull-down when the HE4056 in a charge cycle. In other status CHRG in high impedance,CHRG and are all in high impedance when the battery out of the normal temperature.Represent in failure state, when TEMP pin in typical connecting, or the charger with no battery: red LED and green LED all don ’t light. The battery temperature sense function is disabled by connecting TEMP pin to GND. If battery is not connected to charger,CHRG pin outputs a PWM level to indicate no battery. If BAT pin connects a 10μF capacitor, the frequency of CHRG flicker about 1-4S, If not use status indicator should set status indicator output connected to GND.The values of R1 and R2 in the application circuit can be determined according to the assumed temperature monitor range and thermistor ’s values. The Follows is an example: Assume temperature monitor range is TL ～TH ，(TL ＜TH)；the thermistor in battery has negative temperature coefficient （NTC ），RTL is thermistor ’s resistance at TL ， RTH is the resistance atTH ，so RTL ＞RTH ，then at temperature TL, the voltage at TEMP pin is:INTHTHTEMPH V R R R R R V ⨯+=////212At temperature TH, the voltage at TEMP pin is:INTLTLTEMPL V R R R R R V ⨯+=////212We know VTEMPL ＝VHIGH ＝K2×Vcc (K2=0.8)；VTEMPH ＝VLOW ＝K1×Vcc (K1=0.45) Then we can have ：12121)()(K K R R K K R R R TH TL TH TL ⨯--⨯=;)()()(212211121K K K R K K K R K K R R R TH TL TH TL ⨯--⨯--⨯=Likewise, for positive temperature coefficient thermistor in battery, we have RTH ＞RTL and we can calculate:12121)()(K K R R K K R R R TL TH TH TL ⨯--⨯=;)()()(212211121K K K R K K K R K K R R R TL TH TH TL ⨯--⨯--⨯=We can conclude that temperature monitor range is independent of power supply voltage VCC and it only depends on R1, R2, RTL and RTH: The values of RTH and RTL can be found in related battery handbook or deduced from testing data. In actual application, if only one terminal temperature is concerned (normally protecting overheating), there is no need to use R2 but R1. It becomes very simple to calculate R1 in this case.Block Diagram1.1A Lithium Ion Battery Linear Charger1.1A Lithium Ion Battery Linear ChargerC210uF1.1A Lithium Ion Battery Linear ChargerPackaging Information:SOP8 PACKAGE OUTLINE DIMENSIONS。
