MIC4426YMM

Microchip Tech · Gate Drive ICs · MSOP-8

MIC4426YMM 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: TTL/CMOS compatible logic input; inverting for MIC4426, threshold approximately 1.5V with 100 mV hysteresis, protected to -5V.
3 GND power_in Ground; can withstand up to 5V noise spikes of either polarity.
4 INB input Control Input B: TTL/CMOS compatible logic input; inverting for MIC4426, threshold approximately 1.5V with 100 mV hysteresis, protected to -5V.
5 OUTB output Output B: CMOS totem-pole output with 1.5A peak current that swings within 25 mV of supply or ground.
6 VS power_in Supply Input: +4.5V to +18V operating range (22V absolute maximum).
7 OUTA output Output A: CMOS totem-pole output with 1.5A peak current that swings within 25 mV of supply or ground.
8 NC unconnected Not internally connected.
