IX4351NE9A Low Side I SiC MOSFET & IGBT Driver NTEGRATED CIRCUITS DIVISION FeaturesDescription• 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 charge pump regulator for selectable source and sink outputs allow for tailored turn-on and 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, IN, 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.
