Ordering Information
- XXXX= date code Pin Function TEMP (Pin 1): Battery temperature detection input. TEMP pin to receive the battery NTC sensor output. If the TEMP pin voltage is less than the input voltage is greater than 45% or 80% of the input voltage means the battery temperature is too low or too high, then the charge has been suspended. If the TEMP direct access GND, battery temperature detection canceled, the other charged and functioning properly. PROG (Pin 2): Charge Current Program, Charge Current Mon itor and Shutdown Pin. The charge current is programmed by connecting a 1% resistor, R PROG, to ground. When charging in trickle-current mode, this pin servos to 0.1V.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) • 1000. 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 P ROG 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 w ill draw currents as high as 1.5mA. Reconnecting R PROG 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 10 uF capacitor. When VCC drops to with in 30mV of the BAT pin voltage, the AP5057 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 would AP5057 is in normal working condition; low input level so that AP5057 is prohibited charging status. CE pin can be TTL or CMOS level-level driver. V2.0 5 / 7
