MIC4421A/4422A
9A Peak Low-Side MOSFET Driver Bipolar/CMOS/DMOS Process
General Description
Features
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. Additional circuits protect against damage from electrostatic discharge.
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 Low delay time: 15ns (typ.) .
