MIC4420/4429
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 larg-
est MOSFETs with an improved safe operating margin. The
MIC4420/4429/429 accepts any logic input from 2.4V to V
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.
MIC4420/4429/429 drivers can replace three or more
discrete 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.
Note: See MIC4120/4129 for high power and narrow
pulse applications.
