IX4351NE 9A Low-Side SiC MOSFET & IGBT Driver

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 overcurrent 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 an operational temperature range of -40°C to +125°C and is available in a thermally enhanced 16-pin power SOIC package.
