Microchip Technology TC4421CPA High-Speed MOSFET Driver
The TC4421/TC4422 are high-speed, high-current MOSFET drivers capable of delivering up to 9A peak output current. Designed for driving large MOSFETs and IGBTs, these inverting and non-inverting buffer drivers feature low propagation delay, fast rise and fall times, and wide input voltage operation from 4.5V to 18V. Their robust protection includes latch-up immunity, reverse current withstand, electrostatic discharge protection, and noise immunity from built-in hysteresis. Ideal for line drivers, pulse generators, motor switching, and power switching applications, they support both surface-mount and through-hole packages for versatile integration in industrial environments.
