FAN6240M6X

FAN6240M6X from onsemi, 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 GATE output Gate drive output for the external synchronous rectifier MOSFET. Push-pull driver swings between GND (VOL <= 0.25 V) and VDD (VOH ~5 V) with ~10 ns rise/fall time into 3.3 nF load.
2 GND power_in Device ground reference. All voltages are specified with respect to this pin.
3 VDD power_out Internal 5 V LDO output and gate-drive power-supply rail (typ 5.25 V, recommended 2.8-6 V). Bypass with a 1 uF capacitor to GND.
4 VIN power_in LDO input, supports up to 30 V absolute max (recommended 2.8-20 V). Feeds the integrated 5 V LDO that generates the internal VDD rail for the low-voltage control circuitry. UVLO turn-on 3.4 V typ, turn-off 2.9 V typ.
5 SOURCE input Synchronous rectifier source sense input. Compared against the DRAIN pin (via VTH_OFF ~10 mV) to detect the SR turn-off point when MOSFET current decreases to near zero. Rated -0.3 V to 1 V.
6 DRAIN input Synchronous rectifier drain sense input. Monitors the SR MOSFET drain voltage; when it drops below VTH_ON (~-210 mV) with sufficient slope, the controller triggers the gate turn-on. Rated -1 V to 100 V absolute max.
