MIC4607A-1YMLVAO

Overview

The MIC4607A-1YMLVAO is an 85V three-phase MOSFET driver designed for robust motor control applications. It features a fast 35ns propagation delay and 20ns rise/fall times for 1nF capacitive loads. The device supports gate drive supply voltages up to 16V and includes adaptive dead-time, anti-shoot-through protection, and overcurrent protection with blanking time insertion. It drives high-side and low-side N-channel MOSFETs via independent inputs or a single PWM signal. The component operates within a junction temperature range of -40°C to +125°C and is housed in a 28-pin 4mm x 5mm VQFN package.

Feature Summary
