TP4060

TOPPOWER Nanjing Extension Microelectronics · Battery Management · SOIC-8-EP

TP4060 from TOPPOWER Nanjing Extension Microelectronics, in a SOIC-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection. Grounding is recommended.
2 PROG bidirectional Charge-current program, monitor, and shutdown pin. A resistor RPROG (1% tolerance) between PROG and GND sets IBAT per IBAT=1000/RPROG (up to 0.3A) or 1000/RPROG*(1.3-IBAT) above 0.3A; the pin sits at ~1V in constant-current mode. Disconnecting RPROG lets an internal 2.5uA pull-up raise PROG above the 2.7V shutdown threshold to disable the charger.
3 STDBY output Open-drain standby (charge-complete) indicator, active low. Pulled low by an internal switch when charging is complete; otherwise high-impedance. Typical VOL 0.3V at 5mA sink.
4 VCC power_in Input supply, 4V to 9V (absolute max 9V). Bypass with at least 1uF. When VCC drops within 30mV of BAT, the part enters shutdown and IBAT falls below 2uA.
5 BAT power_out Charge current output to the single-cell Li-Ion battery. An internal resistor divider regulates the float voltage to 4.2V (+/-1%). In shutdown the divider is disconnected. Continuous short-circuit tolerant; max BAT pin current 500mA absolute.
6 GND power_in Ground return for the device.
7 CHRG output Open-drain charge-status indicator, active low. Pulled low while the battery is being charged; high-impedance otherwise. Typical VOL 0.3V at 5mA sink; typically drives an LED to ground through a series resistor.
8 NC unconnected No internal connection. Grounding is recommended.
