IX4351NE IXYS

IX4351NE 9A Low Side SiC MOSFET & IGBT Driver INTEGRATED CIRCUITS DIVISION Features Description Separate 9A peak source and sink outputs The IX4351NE is designed specifically to drive SiC Operating Voltage Range: -10V to +25V MOSFETs and high power IGBTs. Separate 9A Internal negative charge pump regulator for source and sink outputs allow for tailored turn-on and selectable negative gate drive bias turn-off timing while minimizing switching losses. An Desaturation detection with soft shutdown sink driver internal negative charge regulator provides a TTL and CMOS compatible input selectable negative gate drive bias for improved dV/dt Under Voltage lockout (UVLO) immunity and faster turn-off. Thermal shutdown Open drain FAULT output Desaturation detection circuitry detects an over current condition of the SiC MOSFET and initiates a Applications soft turn off, thus preventing a potentially damaging Driving SiC MOSFETs and IGBTs dV/dt event. The logic input is TTL and CMOS On-board charger and DC charging station compatible this input does not need to be level shifted Industrial inverters even with a negative gate drive bias voltage. PFC, AC/DC and DC/DC converters Protection features include UVLO and thermal shutdown detection. An open drain FAULT output signals a fault condition to the microcontroller.
