MIC4421A/4422A 9A Peak Low-Side MOSFET Driver Bipolar/CMOS/DMOS Process General Description Features MIC4421A and MIC4422A MOSFET drivers are rugged, ? High peak-output current: 9A Peak (typ.) efficient, and easy to use. The MIC4421A is an inverting ? Wide operating range: 4.5V to 18V (typ.) driver, while the MIC4422A is a non-inverting driver. ? Minimum pulse width: 50ns Both versions are capable of 9A (peak) output and can ? Latch-up proof: fully isolated process is inherently drive the largest MOSFETs with an improved safe immune to any latch-up operating margin. The MIC4421A/4422A accepts any logic ? Input will withstand negative swing of up to 5V input from 2.4V to V without external speed-up capacitors S ? High capacitive load drive: 47,000pF or resistor networks. Proprietary circuits allow the input to ? Low delay time: 15ns (typ.) swing negative by as much as 5V without damaging the ? Logic high input for any voltage from 2.4V to V part. Additional circuits protect against damage from S ? Low equivalent input capacitance: 7pF (typ.) electrostatic discharge. ? Low supply current: 500?A (typ.) MIC4421A/4422A drivers can replace three or more discrete components, reducing PCB area requirements, ? Output voltage swing to within 25mV of GND or V S simplifying product design, and reducing assembly cost. Modern Bipolar/CMOS/DMOS construction guarantees Applications freedom from latch-up. The rail-to-rail swing capability of ? Switch mode power supplies CMOS/DMOS insures adequate gate voltage to the MOSFET during power up/down sequencing. Since these ? Motor controls devices are fabricated on a self-aligned process, they have ? Pulse transformer driver very low crossover current, run cool, use little power, and ? Class-D switching amplifiers are easy to drive. ? Line drivers Data sheets and support documentation can be found on ?
