**Diodes Incorporated** · Battery Management · SOT-25

AP9101CAK-ABTRG1 from Diodes Incorporated, in a SOT-25. 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 | VM | input | Charger negative input pin, which must stay within the datasheet charger input voltage of -0.3 V to 30 V relative to VDD (absolute maximum), with 5.5 V as the recommended maximum. |
| 2 | VDD | power_in | Positive power input pin, with recommended supply voltage between VDD and VSS of 1.5 V to 5.5 V and an absolute maximum of 12 V. |
| 3 | VSS | power_in | Negative power input pin and the reference ground for the supply voltage between VDD and VSS. |
| 4 | DO | output | FET gate control pin for discharge, with output voltage limited to VSS-0.3 V to VDD+0.3 V. |
| 5 | CO | output | FET gate control pin for charge, with output voltage limited to VM-0.3 V to VDD+0.3 V. |
