AP9101CAK-ATTRG1

Diodes Incorporated · Battery Management ICs · SOT-25

AP9101CAK-ATTRG1 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, used with R2 (300Ω to 4kΩ, typical 2.7kΩ) to monitor charger status and charge/discharge current.
2 VDD power_in Positive power input pin; supply between VDD and VSS is 1.5V to 5.5V per the recommended operating conditions, with R1 (330Ω to 470Ω) and C1 (10nF to 1000nF) stabilizing the supply.
3 VSS power_in Negative power input pin (ground reference for the supply and the DO/CO gate drivers).
4 DO output FET gate control pin for discharge, driving the discharge MOSFET.
5 CO output FET gate control pin for charge, driving the charge MOSFET.
