General Description

MIC4120 and MIC4129 MOSFET drivers are resilient,

efficient, and easy to use. The MIC4129 is an inverting

driver, while the MIC4120 is a non-inverting driver. The

MIC4120 and MIC4129 are improved versions of the

MIC4420 and MIC4429.

The drivers are capable of 6A (peak) output and can drive

the largest MOSFETs with an improved safe operating

margin. The MIC4120/4129 accept any logic input from

2.4V to V

tor networks. Proprietary circuits allow the input to swing

negative by as much as 5V without damaging the part. Ad-

ditional circuits protect against damage from electrostatic

discharge.

MIC4120/4129 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.
