Gate Drivers ICs

MIC4421YM Description

The MIC4421YM from Microchip Technology is a high-performance, low-side gate driver IC designed for demanding power electronics applications. Housed in an 8-pin SOIC package, it features a single-channel, inverting input configuration with robust 4.5V to 18V supply voltage support. The device delivers peak output currents of 9A (source/sink), enabling fast switching of MOSFETs and IGBTs with rise/fall times as low as 20ns/24ns. Its low propagation delay and high noise immunity (VIL/VIH: 0.8V/2.4V) make it suitable for precision-driven systems. Compliant with ROHS3 and REACH standards, it is ideal for industrial, automotive, and power management applications.
