Microchip Tech · Gate Drivers · SOIC-8
MIC4427YM-TR from Microchip Tech, 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 | NC | unconnected | Not internally connected. |
| 2 | INA | input | Control Input A is a TTL/CMOS compatible logic input with a threshold of approximately 1.5V and 100 mV of hysteresis, and unused inputs must be tied to logic high (VS) or ground. |
| 3 | GND | power_in | Ground return for the driver; the datasheet recommends separate input and output ground returns or a ground plane for optimum switching speed, and inputs may be driven to -5V below ground. |
| 4 | INB | input | Control Input B is a TTL/CMOS compatible logic input with a threshold of approximately 1.5V and 100 mV of hysteresis, and unused inputs must be tied to logic high (VS) or ground. |
| 5 | OUTB | output | Output B is a CMOS totem-pole driver output rated for 1.5A peak current and swinging to within 25 mV of VS or ground. |
| 6 | VS | power_in | Supply input; the operating range is +4.5V to +18V, with an absolute maximum of +22V. |
| 7 | OUTA | output | Output A is a CMOS totem-pole driver output rated for 1.5A peak current and swinging to within 25 mV of VS or ground. |
| 8 | NC | unconnected | Not internally connected. |
