General Description
●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 VSwithout 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.
●Features
●• 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 isinherently 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.)
●• Logic high input for any voltage from 2.4V to VS
●• Low equivalent input capacitance: 7pF (typ.)
●• Low supply current: 500µA (typ.)
●• Output voltage swing to within 25mV of GND or VS
