# AP5054BES5C

**Wuxi Chipown Micro-electronics** · Battery Management · SOT-23-5

AP5054BES5C from Wuxi Chipown Micro-electronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CHRG | output | Open-drain charge status output that is pulled low through an internal N-channel MOSFET while charging and goes high-impedance when the charge cycle completes or the part is in undervoltage lockout; V_CHRG is 1.5 V max at I_CHRG = 1 mA. |
| 2 | GND | power_in | Power ground reference for the charger. |
| 3 | BAT | power_out | Battery connection that supplies charge current and regulates the final float voltage to 4.2 V (V_float 4.16 V to 4.24 V at 0 °C to 85 °C). |
| 4 | VCC | power_in | Charger input supply, 4.25 V to 5.5 V, which requires a capacitor of at least 1 µF; the input OVP threshold is 5.75 V to 6.3 V. |
| 5 | PROG | passive | For AP5054BES5C, a 1% precision resistor from this pin to GND sets the charge current via I_BAT = (V_PROG / R_PROG) × 1000, with V_PROG held at 1 V in constant-current mode; a shutdown threshold of 1.21 V applies when the resistor is disconnected. |

## CAD (land: KiCad; 3D: generated from the datasheet)

- Symbol: `AP5054BES5C`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5, generated on the KiCad land (body 1.6 x 2.95 mm, terminals on the pads, 1.15 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
- 3D model files: `ap5054bes5c-etched.step` / `ap5054bes5c-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ap5054bes5c.step` / `ap5054bes5c.glb` are the bare package body.
