MIC4427YMM-TR

Microchip Tech · Gate Drivers · MSOP-8

MIC4427YMM-TR from Microchip Tech, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection. Leave floating or tie to ground.
2 INA input Logic input A. TTL/CMOS compatible; inverting input to driver A. Input threshold ~1.5V, independent of VS supply voltage.
3 GND power_in Ground return. Common ground for logic input and high-current output driver stages. Must be a low-impedance connection due to peak currents up to 1.5A.
4 INB input Logic input B. TTL/CMOS compatible; inverting input to driver B. Input threshold ~1.5V, independent of VS supply voltage.
5 OUTB output Driver B output. CMOS totem-pole output capable of sourcing/sinking 1.5A peak into capacitive loads. Inverted with respect to INB.
6 VS power_in Supply voltage input, 4.5V to 18V. Bypass with a low-ESR capacitor (typ. 1µF ceramic + bulk) close to the pin to handle the fast transient currents.
7 OUTA output Driver A output. CMOS totem-pole output capable of sourcing/sinking 1.5A peak into capacitive loads. Inverted with respect to INA.
8 NC unconnected No internal connection. Leave floating or tie to ground.
