MX22917T23 from Wuxi Maxinmicro, in a SOT-23-6. 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 VIN power_in Load switch input supply, 1 V to 5.5 V. Source pin of the internal P-channel pass MOSFET. Decouple with input capacitor (typ. 1 µF) placed close to the pin.
2 GND power_in Device ground reference. Return for control logic, charge pump, and quick output discharge FET.
3 ON input Active-high switch control input (MX22917T, non-inverting). Compatible with standard GPIO logic thresholds; VIH ≈ 1.05-1.09 V. A smart pulldown (~750 kΩ, RPD) keeps the pin from floating at power-up. Do not leave floating.
4 CT passive Switch slew-rate / turn-on-time control. Connect a capacitor from CT to VIN to slow the VOUT slew rate and lengthen turn-on time; leave floating for fastest turn-on (~120 µs at 5 V). CT = (Slew Rate) / SR_ON.
5 QOD passive Quick output discharge pin. When the switch is disabled, VOUT is pulled down through this pin. Three usage modes: (1) external resistor R_QOD between VOUT and QOD sets discharge rate, (2) tie QOD directly to VOUT to use the internal ~150 Ω pulldown (RPD/QOD), or (3) leave floating to disable QOD.
6 VOUT power_out Load switch output. Drain of the internal P-channel pass MOSFET. Delivers up to 2 A continuous with typical RON = 100 mΩ at VIN = 5 V.
