TECH PUBLIC · Battery Management · SOT-23-5

TP4054S5 from TECH PUBLIC, in a SOT-23-5. 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 CHRG output Open-drain charge status output. Pulled low by an internal N-channel MOSFET during charging; high-impedance when charging completes or when the part detects an under-voltage-lockout condition. Drives an external LED (typ. via 1 kΩ to VCC); with a 1 µF cap from BAT to GND the LED flashes rapidly when no battery is present.
2 GND power_in Device ground return.
3 BAT power_out Charge current output to the Li-ion cell. Sources up to 500 mA and regulates the final float voltage to 4.2 V. Auto-disconnects from VCC when the charger is disabled or in shutdown; internal protection allows ~1 mA to flow between GND and BAT when the battery is reverse-connected, protecting the ESD diode.
4 VCC power_in Positive supply input from the USB or adapter source. Operating range 4.3 V-7 V (absolute max 11 V); requires 0.1 µF-1 µF local decoupling. When VCC - VBAT drops below 30 mV the part enters sleep mode and BAT current falls below 2 µA.
5 PROG input Charge-current program, monitor, and shutdown pin. A 1% resistor to GND sets IBAT = (VPROG / RPROG) × 1000 (e.g. RPROG = 2 kΩ → 500 mA, 10 kΩ → 100 mA); pin sits at ~1 V in constant-current mode. Disconnecting RPROG lets an internal 2.5 µA source pull PROG above the 1.0 V manual-shutdown threshold, stopping charging and dropping ICC to ~40 µA.
