FAN3229TMX

onsemi · Gate Drive ICs · SOIC-8

FAN3229TMX from onsemi, in a SOIC-8. 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 INA+ input Non-inverting input to Channel A; connect to VDD to enable the output.
2 INA− input Inverting input to Channel A; connect to GND to enable the output.
3 GND power_in Ground; common ground reference for input and output circuits.
4 INB+ input Non-inverting input to Channel B; connect to VDD to enable the output.
5 OUTB output Gate drive output B; held LOW unless the required input(s) are present and VDD is above the UVLO threshold.
6 VDD power_in Supply voltage that provides power to the IC; recommended operating range is 4.5 V to 18.0 V.
7 OUTA output Gate drive output A; held LOW unless the required input(s) are present and VDD is above the UVLO threshold.
8 INB+ input Inverting input to Channel B; connect to GND to enable the output.
