MIC4420/4429
6A-Peak Low-Side MOSFET Driver
Bipolar/CMOS/DMOS Process
General Description
MIC4420, MIC4429 and MIC429 MOSFET drivers are
tough, efficient, and easy to use. The MIC4429 and MIC429
are inverting drivers, while the MIC4420 is a non-inverting
driver.
They are capable of 6A (peak) output and can drive the
largest MOSFETs with an improved safe operating mar-
gin. The MIC4420/4429/429 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 electro-
static discharge.
MIC4420/4429/429 drivers can replace three or more dis-
crete components, reducing PCB area requirements,
simplifying product design, and reducing assembly cost.
Modern BiCMOS/DMOS construction guarantees freedom
from latch-up. The rail-to-rail swing capability insures ad-
equate gate voltage to the MOSFET during power up/
down sequencing.
