IXYS, a division of Littelfuse, has begun mass production of the IX4351NE IC, designed to drive SiC MOSFETs and high power IGBTs. Separate 9 A 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, IN, 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.
