# AP5054CES6

**Wuxi Chipown Micro electronics** · Battery Management · SOT-23-6L

AP5054CES6 from Wuxi Chipown Micro electronics, 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 indicator. Pulled low through an internal N-channel MOSFET while the battery is charging; high-impedance when the charge cycle completes or the part enters UVLO. Rated for Ichrg up to ~5 mA with Vol ≈ 0.68-0.8 V. |
| 2 | GND | power_in | Device power ground reference. |
| 3 | BAT | power_out | Battery connection pin. Sources charge current to a single-cell Li-ion battery and regulates the final float voltage to 4.2 V via an internal precision resistor divider. Disconnected in shutdown mode; absolute-maximum current 750 mA. |
| 4 | VCC | power_in | Positive supply input for the charger. Operating range 4.25 V to 6.5 V; bypass with at least 1 µF to GND. When VCC - VBAT falls below ~30 mV the part enters shutdown and IBAT drops below 2 µA. |
| 5 | STDBY | output | Open-drain end-of-charge status indicator. Pulled low through an internal switch when the charge cycle is complete, otherwise high-impedance. Rated for Istdby up to ~5 mA with Vol ≈ 0.68-0.8 V. |
| 6 | PROG | bidirectional | Charge current program, monitor and shutdown pin. Connect a 1% resistor RPROG from PROG to GND to set charge current: IBAT = (VPROG / RPROG) × 1000. VPROG is regulated to 0.1 V in trickle/precharge and 1 V in constant-current mode. Disconnecting RPROG lets an internal 3 µA source pull PROG above the 1.21 V shutdown threshold, driving the charger into shutdown (Icc ≈ 25 µA); the pin is internally clamped at ~2.4 V. |
