Introduction

AI Translation

COS4421/4422 are single-channel, high-current low-side gate drivers capable of driving large MOSFETs, SiC, GaN, and IGBTs. The unique circuit design enables high-speed operation, delivering 9A peak current into a 10,000pF capacitive load. Matched rise and fall delay times enhance speed and drive capability. Non-overlapping drive technology minimizes dynamic switching losses. These devices offer high latch-up immunity across their power and voltage ratings. Noise spikes up to 5V (either polarity) on the ground pin will not damage the device. The COS4421/4422 inputs can be driven directly by TTL or CMOS (1.6V ~ 25V). In addition, 300mV built-in hysteresis provides noise immunity and allows the device to be driven by slowly rising or falling waveforms. If the input is unbiased or floating, the output remains low.
