# TP4069-4.2V-SOT236

**TOPPOWER(Nanjing Extension Microelectronics)** · Battery Management · SOT-23-6L

TP4069-4.2V-SOT236 from TOPPOWER(Nanjing Extension Microelectronics), in a SOT-23-6L. 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 charging status indicator output, pulled low while charging and high-impedance otherwise; connect to ground if unused. |
| 2 | GND | power_in | Power supply ground. |
| 3 | BAT | bidirectional | Charger output connected to the battery terminal; absolute maximum -4.2V to 7V, 900mA pin current. |
| 4 | VCC | power_in | Chip power input terminal; input supply 4.35V to 9.0V, absolute maximum 0V to 9V. |
| 5 | TS | input | Battery temperature detection input; charging pauses when VTS is below 45% or above 80% of VCC, and tying it to ground disables the function. |
| 6 | PROG | bidirectional | Charging current setting via a resistor to ground, charging current monitoring, and shutdown when floated; absolute maximum 2mA pin current. |
