TP4083-42-SOT236 from TOPPOWER Nanjing Extension Microelectronics, in a SOT-23-6L. 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 switch while the battery is charging; high-impedance otherwise. Output low voltage ~2V at I=3mA; leakage <1uA at 5V. |
| 2 | GND | power_in | Ground terminal / device return. |
| 3 | BAT | power_out | Battery connection pin. Sources charge current to the single-cell Li-Ion battery and regulates the final float voltage to 4.2V (±1%). Internal resistor divider is disconnected in shutdown to minimize battery drain (<1uA when VCC is within 80mV of VBAT). |
| 4 | VCC | power_in | Positive input supply (4.2V-25V absolute; typical 5V). Chip enters OVP shutdown when VCC exceeds ~16V (VOVP). Requires ≥4.7uF X5R ceramic decoupling close to the pin. UVLO ~3.8V. |
| 5 | STDBY | output | Open-drain charge-status output. Pulled low by an internal switch upon charge termination (standby); high-impedance otherwise. Output low ~2V at I=3mA; leakage <1uA at 5V. |
| 6 | PROG | bidirectional | Charge-current setting, charge-current monitoring, and shutdown pin. A 1%-precision resistor RPROG from PROG to GND sets IBAT (e.g. 10kΩ→110mA, 1.91kΩ→500mA). PROG servos to ~1V in constant-current mode. A 0.2uA internal pull-up drives PROG high when the resistor is removed; if PROG exceeds ~2.7V the charger enters shutdown. |
