XC5101-1A线性锂离子电池充电器

XC5101_______________________________________________________XC5101- 1A Linear Li-Ion Battery Charger GENERAL DESCRIPTIONThe XC5101 is a complete constant current &constant voltage linear charger for single cell lithium-ion batteries. Its SOP package and low external component count make the XC5101 ideally suited for portable applications.Furthermore, the XC5101 is specifically designed to work within USB power specifications.No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. Thermal feedback regulates the charge current to limit the dietemperature during high power operation or high ambient temperature. The charge voltage is fixed at 4.21V, and the charge current can beprogrammed externally with a single resistor. The XC5101 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 XC5101 automatically enters a low current state, dropping the battery drain current to less than 2uA. The XC5101 can be put into shutdown mode, reducing the supply current to 50uA.Other features include Battery temperature monitor, under-voltage lockout, automaticrecharge and two status pins to indicate charge and charge termination.FEATURESProgrammable Charge Current Up to 1000mANo MOSFET, Sense Resistor or Blocking DiodeComplete Linear Charger in SOP Package for single Cell Lithium-Constant-Current/Constant-Voltage Operation with Thermal Regulation to Maximize ChargeRate Without Risk of OverheatingCharges Single Cell Li-Ion Batteries Directly fromPreset 4.21V Charge Voltage with ±1% AccuracyCharge Current Monitor Output for Gas GaugingCharge state pairs of output, no battery and faultC/10Soft-Available in SOP8-PP PackageAPPLICATIONSCellular Telephones, PDAs, MP3 /MP4 PlayersCharging Docks and Cradles Bluetooth 、GPS ApplicationsFigure1Typical Application Circuit深圳市思微半导体有限公司XC5101 ______________________________________________________________________________________________________________________ ORDERING INFORMATIONPART NUMBER TEMP RANGE VIN VBATCHARGECURRENTPACKAGE PINSXC5101 -40°C to 85°C 4.5~6V 4.21V 1A SOP-PP 8 PIN CONFIGURATIONFigure 2.

When charging in constant-current mode, this pin servos to 1V. In all modes, the voltage on this pin can be used to measure the charge current using the following formula: IBAT = (VPROG/RPROG) x1000.The PROG pin can also be used to shut down the charger. Disconnecting the program resistor from ground allows a 3uA current to pull the PROG pin high. When it reaches the 1.21V shutdown threshold voltage, the charger enters shutdown mode, charging stops and the input supply current drops to 50uA. This pin is also clamped to approximately 2.4V. Driving this pin to voltages beyond the clamp voltage will draw currents as high as 1.5mA. Reconnecting RPROG to ground will return the charger to normal operation.GND (PIN 3): Ground.VCC (PIN 4): Positive Input Supply Voltage.Provides power to the charger, VCC can range from 4.25V to 6.5V and should be bypassed with at least a 10uF capacitor. When VCC drops to within 30mV of the BAT pin voltage, the XC5101 enters shutdown mode, dropping IBAT to less than 2uA.BAT (PIN 5): Charge Current Output.Provides charge current to the battery and regulates the final float voltage to 4.2V. An internal precision resistor divider from this pin sets the float voltage which is disconnected in shutdown mode.STDBY (PIN 6): The completion of battery charging instructions side.When the battery charge is complete, STDBY pulled low by internal switches, indicating the completion of charging. In addition, STDBY pin will be in a high-impedance state.CHRG (PIN 7): Open-Drain Charge Status Output.When the battery is charging, the CHRG pin is pulled low by an internal N-channel MOSFET. When the charge cycle is completed, CHRG pin will be in a high-impedance state.CE (PIN 8): Chip enable input.High input level will make XC5101 in normal working condition; low input level so that XC5101 is prohibited charging status.

八、功能描述
启动电压及电流
典型的启动电流为5uA ，可以使用阻值较大而功耗较小的启动电阻，以减小功率损耗。

当
V DD 电压上升到15.5V 时，电路开始启动工作，V DD 滤波电容持续对电路供电直到由变压器的辅助绕组提供电流。

在此期间V DD 电压不能低于9.5V 。

一个1.5~2M Ω，0.25W 的启动电阻和一个10uF/25V 的电解电容可满足电源的启动需要。

轻载跳周期工作
在空载或轻载的情况下，FB的电压自动降低。

当V FB < 1.4V且V DD> 10 V时电路会进入间歇振荡状态，震荡输出将停止一段时间，减少开关次数，降低开关损耗。

当V FB>1.4V时，电路进入正常工作状态。

振荡频率和抖频
内置工作频率典型值为67KHz，由于频率抖动功能的作用，开关频率在63K到71K之间变化，以减小某一个频率点对外的辐射，从而降低了EMI，更容易满足设计要求，
前沿消隐
在MOS开启的瞬间，由于寄生电容和次级整流管反向恢复时间等原因，在电流检测电阻上将会有一个尖峰电压。

TM5101内置了350nS的前沿消隐电路，可以屏蔽尖峰电压，避免了电路的误动作，省去了常用的RC滤波器。

峰值电流补偿
由于电路内部的信号传送延时，使电感电流发生额外过冲。

传播延时的时间并不因输入电压变化而变化，但电感电流的过冲量随输入电压升高而陡增，高输入电压和低输入电压条件下的最大输出功率相差甚远。

TM5101通过引入一个动态变化的斜坡电压来均衡高低压输出特性。

过流检测电压限值随占空比的变化从0.8~1.0V
斜坡补偿
在CCM状态下工作时，如果占空比大于50%时，电路容易出现次谐波振荡，TM5101内置斜坡补偿电路可以有效防止次谐波振荡的出现。

V DD过压、欠压保护
当V DD>23V时，电路会进入过压保护，输出脉冲会立即停止，直到V DD掉到欠压后电路重新启动，另外V DD还设置了钳位电路，防止过高的V DD冲击电压损坏电路。

如果V DD电压下落到8.5V以下时电路将会发生欠压保护，电路停止工作。

逐周期电流限制保护
在每个周期，峰值电流都不会超过峰值电流限流值。

当电流达到峰值限流电流后，输出功率就不能再变大，导至FB的电压升高，发生过载保护。

过载或系统开环保护、输出短路保护
当发生开环(反馈环路发生故障，如光耦开路)、过功率、输出短路等异常时，FB引脚的电压会上升，当V FB>3.7V 时，将恒定输出功率，如果此异常维持50mS以上，电路关闭输出，直到V DD欠压后电路重新启动。
