 MIC4421A
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.)
Logic high input for any voltage from 2.4V to VS
Low equivalent input capacitance: 7pF (typ.)
MIC4421A/4422A drivers can replace three or more
discrete components, reducing PCB area requirements,
simplifying product design, and reducing assembly cost.
Low supply current: 500µA (typ.)
Output voltage swing to within 25mV of GND or VS
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.
