MIC4421A and MIC4422A MOSFET drivers are rugged, efficient, and easy to use. The MIC4421A is an inverting driver, while the MIC4422A is a non-inverting driver. Both versions are capable of 9A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4421A/4422A accepts any logic input from 2.4V to VS without external speed-up capacitors or resistor networks. Proprietary circuits allow the input to swing negative by as much as 5V without damaging the part.
High peak-output current: 9A peak (typ.) Wide operating range: 4.5V to 18V (typ.) Minimum pulse width: 50ns Latch-up proof: fully isolated process is inherently immune to any latch-up. Input will withstand negative swing of up to 5V High capacitive load drive: 47,000pF High peak-output current: 9A peak (typ.) Wide operating range: 4.5V to 18V (typ.) Minimum pulse width: 50ns Latch-up proof: fully isolated process is inherently immune to any latch-up. Input will withstand negative swing of up to 5V
