OB2001MP from OB On Bright Elec, 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 VDD power_in Power supply input. Recommended operating range 4V to 5.5V. UVLO turn-on ~3.1V, turn-off ~3.0V. Minimum regulation voltage 4.2V.
2 GND power_in Ground reference for the IC.
3 GATE output Gate driver output for the external N-channel SR MOSFET. Typical 2A source / 3A sink peak current; VOH >= 4.5V, VOL <= 1V at VDD=5V; ~30ns rise/fall into 1nF. Internal 10k pull-down when in UVLO.
4 VD input Drain-sense input; connects to the drain of the external N-channel SR MOSFET. SR turn-on threshold ~-200mV, turn-off threshold ~-5mV. Rated -2.5V to 50V (with -2.5V limited to the minimum-duty portion of normal operation).
5 RT passive Minimum-on-time programming pin. A resistor from RT to GND sets Tonmin = 8 * RT * 1e-11 (e.g. RT=25k gives ~1.9us). Internal reference Vrt ~1.0V.
6 VIN input System output voltage sense for overshoot detection/clamp. 1st clamp trigger ~5.65V (SR freq <7.5kHz), 2nd clamp trigger ~6.15V; internal discharge path to GND sinks ~100mA when triggered.
