FAN3181TMX
onsemi · Gate Drive ICs · SOIC-8
FAN3181TMX 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 | IN | input | Input signal controls the output, the output is in-phase (non-inverting) with this input, and IN has a 100 k pull-down resistor. |
| 2 | FO/SD | output | Open-drain fault output and shutdown pin that signals the main controller when the driver has detected a fault and deactivated the output. |
| 3 | VCC | power_in | Power supply input whose bypass capacitor to GND must be placed as close as possible to the VCC pin; fixed supply voltage is 25 V max (recommended) and absolute maximum is 30.0 V. |
| 4 | GND | power_in | Ground reference that should connect to the IGBT emitter or shunt resistor with a short trace. |
| 5 | CIN | input | Analog input for over-current detection. |
| 6 | GS | output | Provides active Miller clamping of the IGBT gate during the off period to prevent parasitic turn-on from high collector-to-emitter dv/dt, with the clamp closing when the gate falls below about 1.5 V (typical). |
| 7 | OUT | output | Gate driver output, typically 1.5 A sourcing and 2.0 A sinking at VCC = 15 V. |
| 8 | DESAT | input | Input for detecting IGBT desaturation; a fault is flagged when the DESAT voltage exceeds the typical 6.4 V threshold. |
