IX4351NE
9A Low Side SiC
MOSFET & IGBT Driver
Description
The IX4351NE is designed specifically to drive SiC
MOSFETs and high power IGBTs. Separate 9A
source and sink outputs allow for tailored turn-on and
turn-off timing while minimizing switching losses. An
internal negative charge regulator provides a
selectable negative gate drive bias for improved dV/dt
immunity and faster turn-off.
Desaturation detection circuitry detects an over
current condition of the SiC MOSFET and initiates a
soft turn off, thus preventing a potentially damaging
dV/dt event. The logic input is TTL and CMOS
compatible; this input does not need to be level shifted
even with a negative gate drive bias voltage.
Protection features include UVLO and thermal
shutdown detection. An open drain FAULT output
signals a fault condition to the microcontroller.
The IX4351NE is rated for operational temperature
range of -40°C to +125°C,and is available in a
thermally enhanced 16-pin power SOIC package.
