FAN3217TMX

onsemi · Gate Drivers · SOIC-8

FAN3217TMX from onsemi, in a SOIC-8. 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 NC unconnected No Connect. This pin can be grounded or left floating.
2 INA input Input to Channel A (non-inverting for FAN3217). TTL logic thresholds (VIL 0.8 V typ, VIH 1.6 V typ). Internal 100 kΩ pull-down to GND so an unconnected input defaults LOW; INx range 0 V to VDD.
3 GND power_in Ground. Common ground reference for input and output circuits.
4 INB input Input to Channel B (non-inverting for FAN3217). TTL logic thresholds (VIL 0.8 V typ, VIH 1.6 V typ). Internal 100 kΩ pull-down to GND so an unconnected input defaults LOW; INx range 0 V to VDD.
5 OUTB output Gate Drive Output B (non-inverting, follows INB). Held LOW unless required input(s) are present and VDD is above UVLO threshold. MillerDrive stage delivers ~2.4 A sink / 1.6 A source (peak ±3 A) into MOSFET gate; 0 V to VDD swing.
6 VDD power_in Supply Voltage. Provides power to the IC. Operating range 4.5 V to 18 V (absolute max 20 V); typical UVLO turn-on 3.9 V, turn-off 3.7 V. Bypass locally with a low-ESR ceramic capacitor close to the pin.
7 OUTA output Gate Drive Output A (non-inverting, follows INA). Held LOW unless required input(s) are present and VDD is above UVLO threshold. MillerDrive stage delivers ~2.4 A sink / 1.6 A source (peak ±3 A) into MOSFET gate; 0 V to VDD swing.
8 NC unconnected No Connect. This pin can be grounded or left floating.
