MIC4451/4452
12A-Peak Low-Side MOSFET Driver
Bipolar/CMOS/DMOS Process General Description Features MIC4451 and MIC4452 CMOS MOSFET drivers are
robust, efficient, and easy to use. The MIC4451 is an
inverting driver, while the MIC4452 is a non-inverting
driver.
Both versions are capable of 12A (peak) output and can
drive the largest MOSFETs with an improved safe
operating margin. The MIC4451/4452 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.
MIC4451/4452 drivers can replace three or more discrete
components, reducing PCB area requirements, simplifying
product design, and reducing assembly cost.
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 …
