TECH PUBLIC · Battery Management · SOT-23-5
TP4054S5-2 from TECH PUBLIC, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CHRG | output | Open-drain charge status output; pin voltage rated -0.3V to +11.0V, low-level output 0.25V typ at ICHRG=5mA. |
| 2 | GND | power_in | Ground terminal. |
| 3 | BAT | power_out | Charge current output to the battery; pin voltage rated -0.3V to +11.0V, max 500mA, 4.2V float voltage. |
| 4 | VCC | power_in | Positive supply voltage input; operating 4.2V to 7.5V (5.0V typ), absolute max -0.3V to +11.0V. |
| 5 | PROG | bidirectional | Charge current programming, charge current monitor and shutdown pin; set by a resistor to GND (2K gives 500mA), rated -0.3V to +11.0V. |
