MIC4120/4129 Micrel, Inc. MIC4120/4129
6A-Peak Low-Side Mosfet Driver
Bipolar/CMOS/DMOS Process General Description Features 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 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.
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 adequate gate voltage to the MOSFET during power up/down
sequencing. CMOS Construction
