# FAN7380MX

**onsemi** · Gate Drivers · SOIC-8

FAN7380MX 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 | LIN | input | Logic input for the low-side gate driver output, TTL-compatible and in phase with LO. |
| 2 | HIN | input | Logic input for the high-side gate driver output, TTL-compatible and in phase with HO. |
| 3 | VCC | power_in | Low-side supply voltage, operating range 10 V to 20 V. |
| 4 | COM | power_in | Logic ground and low-side driver return. |
| 5 | LO | output | Low-side gate driver output, typical 90 mA source / 180 mA sink. |
| 6 | VS | power_in | High-side floating supply voltage return, allowed down to -9.8 V (typical) at VBS = 15 V. |
| 7 | HO | output | High-side gate driver output, typical 90 mA source / 180 mA sink. |
| 8 | VB | power_in | High-side floating supply, operating range 10 V to 20 V, for floating operation up to +600 V. |
