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 V S 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.
MIC4421A/4422A drivers can replace three or more
discrete components, reducing PCB area requirements,
simplifying product design, and reducing assembly cost.

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.)
Logic high input for any voltage from 2.4V to V S
Low equivalent input capacitance: 7pF (typ.)
Low supply current: 500μA (typ.)
Output voltage swing to within 25mV of GND or V S
Modern Bipolar/CMOS/DMOS construction guarantees
freedom from latch-up. The rail-to-rail swing capability of
CMOS/DMOS insures adequate gate voltage to the
MOSFET during power up/down sequencing. Since these
devices are fabricated on a self-aligned process, they have
very low crossover current, run cool, use little power, and
are easy to drive.
