MIC4427YMM

Microchip Tech · Gate Drive ICs · MSOP-8

MIC4427YMM from Microchip Tech, in a MSOP-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 that drives output A, with an input current of 1µA maximum between 0 and VS.
3 GND power_in Ground reference for the driver; the datasheet notes that individual ground returns or a ground plane are recommended for optimum switching speed.
4 INB input Control Input B is a TTL/CMOS compatible logic input that drives output B, with an input current of 1µA maximum between 0 and VS.
5 OUTB output Output B is a CMOS totem-pole output that swings within 25mV of the positive supply or ground.
6 VS power_in Supply input rated +4.5V to +18V.
7 OUTA output Output A is a CMOS totem-pole output that swings within 25mV of the positive supply or ground.
8 NC unconnected Not internally connected.
