Its unique topology maintains a constant output voltage with programmable charging current. Its ability to maintain equal voltages on both cells while charging protects the supercapacitors from damage that is possible with other charging methods, without the use of external balancing resistors. The L TC3225 includes an internal switched capacitor charge pump to boost V IN to a regulated output voltage. A unique architecture maintains relatively constant input current for the lowest possible input noise. The basic charger circuit requires only three external components. Normal Charge CycleOperation begins when the SHDN pin is pulled above 1.3V. The C OUT pin voltage is sensed and compared with a preset voltage threshold using an internal resistor divider and a comparator. The preset voltage threshold is 4.8V/5.3V selectable with the V SEL pin. If the voltage at the C OUT pin is lower than the preset voltage threshold, the oscillator is enabled. The oscillator operates at a typical frequency of 0.9MHz. When the oscillator is enabled, the charge pump operates charging up C OUT. The input current drawn by the internal charge pump ramps up at approximately 20mA/μs each time the charge pump starts up from shutdown. Once the output voltage is charged to the preset voltage threshold, the part shuts down the internal charge pump and enters into a low current state. In this state, the L TC3225 consumes only about 20μA from the input supply. The current drawn from C OUT is approximately 2μA. Automatic Cell BalancingThe L TC3225 constantly monitors the voltage across both supercapacitors while charging. When the voltage across the supercapacitors is equal, both capacitors are charged with equal currents. If the voltage across one supercapacitor is lower than the other, the lower supercapacitor’s charge current is increased and the higher supercapacitor’s charge current is decreased. The greater the difference between the supercapacitor voltages, the greater the difference in charge current per capacitor. The charge currents can increase or decrease as much as 50% to balance the volt-age across the supercapacitors. When the cell voltages are balanced, the supercapacitors are charged at a rate of approximately:I ICOUT VIN=12•If the leakage currents or capacitances of the two su-percapacitors are mismatched enough that varying the charging current is not suffi cient to balance their volt-ages, the L TC3225 stops charging the capacitor with the higher voltage until they are again balanced. This feature protects either capacitor from experiencing an overvoltage condition.Shutdown ModeAsserting SHDN low causes the L TC3225 to enter shut-down mode. When the charge pump is fi rst disabled, the L TC3225 draws approximately 1μA of supply current from V IN and C OUT. After V OUT is discharged to 0V, the current from V IN drops to less than 1μA. With SHDN connected to V IN, the output sinks less than 1μA when the input sup-ply is removed. Since the SHDN pin is a high impedance CMOS input, it should never be allowed to fl oat. Output Status Indicator (PGOOD)During shutdown, the PGOOD pin is high impedance. When the charge cycle starts, an internal N-channel MOSFET pulls the PGOOD pin to ground. When the output voltage, V OUT, is within 6% (typical) of its fi nal value, the PGOOD pin becomes high impedance, but charge current continues to fl ow until V OUT crosses the charge termination voltage. When V OUT drops 7% below the charge termination volt-age, the PGOOD pin again pulls low.Current Limit/Thermal ProtectionThe L TC3225 has built-in current limit as well as overtem-perature protection. If the PROG pin is shorted to ground, a protection circuit automatically shuts off the internal charge pump. At higher temperatures, or if the input voltage is high enough to cause excessive self-heating of the part, the thermal shutdown circuitry shuts down the charge pump once the junction temperature exceeds approximately 150°C. It will enable the charge pump once the junction temperature drops back to approximately 135°C. The L TC3225 is able to cycle in and out of thermal shutdown indefi nitely without latch-up or damage until the overcurrent condition is removed.73225f83225fAPPLICATIONS INFORMATIONProgramming Charge CurrentThe charging current is programmed with a single resistor connecting the PROG pin to ground. The program resistor and the input/output charge currents are calculated using the following equations:I V R I IVIN PROGOUTVIN ==36002(with matched outp p ut capacitors)An R PROG resistor value of 2k or less (i.e., short circuit) causes the L TC3225 to enter overcurrent shutdown mode. This mode prevents damage to the part by shutting down the internal charge pump.Power Effi ciencyThe power effi ciency (η) of the L TC3225 is similar to that of a linear regulator with an effective input voltage of twice the actual input voltage. In an ideal regulating voltage doubler the power effi ciency is given by:η222xIDEAL OUT IN OUT OUT IN OUT OUTI P P V I V I V V ===••NAt moderate to high output power the switching losses and quiescent current of the L TC3225 are negligible and the above expression is valid. For example, with V IN = 3.6V , I OUT = 100mA and V OUT regulated to 5.3V , the measured effi ciency is 71.2% which is in close agreement with the theoretical 73.6% calculation.Effective Open-Loop Output Resistance (R OL )The effective open-loop output resistance (R OL ) of a charge pump is an important parameter that describes the strength of the charge pump. The value of this parameter depends on many factors including the oscillator frequency (f OSC ), value of the fl ying capacitor (C FL Y ), the non-overlap time,the internal switch resistances (R S ) and the ESR of the external capacitors. Output Voltage ProgrammingThe L TC3225 has a V SEL input pin that allows the user to set the output threshold voltage to either 4.8V or 5.3V by forcing a low or high at the V SEL pin respectively.Charging Time EstimationThe estimated charging time when the initial voltage across the two output supercapacitors is equal is given by the equation:t C V V I CHRG OUT COUT INIOUT=()•–where C OUT is the series output capacitance, V COUT is thevoltage threshold set by the V SEL pin, V INI is the initial voltage at the C OUT pin and I OUT is the output charging current given by:I V R OUT PROG=1800When the charging process starts with unequal initialvoltages across the output supercapacitors, only the ca-pacitor with the lower voltage level is charged; the other capacitor is not charged until the voltages equalize. This extends the charging time slightly. Under the worst-case condition, whereby one capacitor is fully depleted while the other remains fully charged due to signifi cant leakage current mismatch, the charging time is about 1.5 times longer than normal. Thermal ManagementFor higher input voltages and maximum output current, there can be substantial power dissipation in the L TC3225. If the junction temperature increases above approximately150°C, the thermal shutdown circuitry automatically deactivates the output. To reduce the maximum junction temperature, a good thermal connection to the PC board is recommended. Connecting the GND pin (Pin 8) and the Exposed Pad (Pin 11) of the DFN package to a ground plane under the device on two layers of the PC board can reduce the thermal resistance of the package and PC board considerably.V IN Capacitor SelectionThe type and value of C IN controls the amount of ripple present at the input pin (V IN). To reduce noise and ripple, it is recommended that low equivalent series resistance (ESR) multilayer ceramic chip capacitors (MLCCs) be used for C IN. Tantalum and aluminum capacitors are not recommended because of their high ESR.The input current to the L TC3225 is relatively constant dur-ing both the input charging phase and the output charging phase but drops to zero during the clock non-overlap times. Since the non-overlap time is small (~40ns) these missing “notches” result in only a small perturbation on the input power supply line. Note that a higher ESR capacitor, such as a tantalum, results in higher input noise. Therefore, ceramic capacitors are recommended for their exceptional ESR performance. Further input noise reduction can be achieved by powering the L TC3225 through a very small series inductor as shown in Figure 2.A 10nH inductor will reject the fast current notches, thereby presenting a nearly constant current load to the input power supply. For economy, the 10nH inductor can be fabricated on the PC board with about 1cm (0.4") of PC board trace.Flying Capacitor SelectionWarning: Polarized capacitors such as tantalum or alumi-num should never be used for the fl ying capacitor since it s volt age can reverse upon st art-up of t he LTC3225. Low ESR ceramic capacitors should always be used for the fl ying capacitor.The fl ying capacitor controls the strength of the charge pump. In order to achieve the rated output current, it is necessary to use at least 0.6μF of capacitance for the fl ying capacitor.The effective capacitance of a ceramic capacitor varies with temperature and voltage in a manner primarily determined by its formulation. For example, a capacitor made of X5R or X7R material retains most of its capacitance from –40°C to 85°C whereas a Z5U or Y5V type capacitor loses considerable capacitance over that range. X5R, Z5U and Y5V capacitors may also have a poor voltage coeffi cient causing them to lose 60% or more of their capacitance when the rated voltage is applied. Therefore, when com-paring different capacitors, it is often more appropriate to compare the amount of achievable capacitance for a given case size rather than comparing the specifi ed capacitance value. For example, over rated voltage and temperature conditions, a 4.7μF 10V Y5V ceramic capacitor in a 0805 case may not provide any more capacitance than a 1μF 10V X5R or X7R capacitor available in the same 0805 case. In fact, over bias and temperature range, the 1μF 10V X5R or X7R provides more capacitance than the 4.7μF 10V Y5V capacitor. The capacitor manufacturer’s data sheet should be consulted to determine what value of capacitor is needed to ensure minimum capacitance values are met over operating temperature and bias voltage.V INFigure 2. 10nH Inductor Used for Input Noise Reduction APPLICATIONS INFORMATION93225f103225fTYPICAL APPLICATIONTable 1 contains a list of ceramic capacitor manufacturers and how to contact them.Table 1. Capacitor ManufacturersAVX Kemet Murata Taiyo Yuden Vishay TDKLayout ConsiderationsDue to the high switching frequency and high transient currents produced by the L TC3225, careful board layout is necessary for optimum performance. An unbroken ground plane and short connections to all the external capacitors improves performance and ensures proper regulation under all conditions.The voltages on the fl ying capacitor pins C + and C – have very fast rise and fall times. The high dv/dt values on these pins can cause energy to capacitively couple to adjacent printed circuit board traces. Magnetic fi elds can also be generated if the fl ying capacitors are far from the part (i.e. the loop area is large). To prevent capacitive energy transfer , a Faraday shield may be used. This is a grounded PC trace between the sensitive node and the L TC3225 pins. For a high quality AC ground it should be returned to a solid ground plane that extends all the way to the L TC3225.Table 2.
