OB2009MP 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 VIN input System output voltage detection input. High-voltage tolerant up to 150V. Used for self-supply from the system output to improve efficiency.
2 GND power_in Device ground reference.
3 SDT input Vds falling-edge slope-sensing threshold adjust. Sources ~20uA (ISDT). Threshold selectable: open = 150ns, tied to GND = 120ns, RSDT=50k = 180ns. If not otherwise stated, leave floating.
4 VDD power_in Power supply pin. Recommended operating range 5.5V to 6.5V. Internally regulated (typ 5.5V/6.5V depending on VIN). UVLO enter ~3.3V, exit ~3.6V. Bypass with 1uF cap to GND.
5 GATE output Gate driver output for external N-channel SR MOSFET. Typical 1A source / 3A sink capability. VOH ≥ 6V @ VDD=6.5V; VOL ≤ 0.5V. Absolute max -0.6V to 12V.
6 VD input Drain-sense input; connect to the external N-channel SR MOSFET drain (no more than 50 ohm series resistor recommended between VD and MOS drain). High-voltage tolerant up to 150V. SR turn-on threshold Vth_SR_act ≈ -200mV; adjustable turn-off threshold via series Rd (0.2*Rd mV).
