Packaged in Vishays proprietary MLP 6 mm Delivers up to 50 A continuous current x 6 mm package, SiC783A enables voltage regulator High frequency operation up to 1 MHz designs to deliver currents up to 50 A per phase. Optimized for 12 V input rail applications The internal power MOSFETs utilize Vishays state-of-the-art trench MOSFET technology that delivers 3.3 V PWM logic with tri-state threshold industry benchmark performance to significantly reduce Zero current detect control for light load efficiency switching and conduction losses. improvement. The SiC783A incorporates an advanced MOSFET gate Short PWM propagation delay (< 20 ns) driver IC that features high current driving capability, Thermal monitor flag adaptive dead-time control, an integrated bootstrap Faster disable Schottky diode, and a thermal warning (THWn) that alerts the system of excessive junction temperature. This driver is V under voltage lock out (UVLO) CIN compatible with wide range of PWM controllers and supports tri-state PWM logic (3.3 V) as well as zero current APPLICATIONS detect to improve light load efficiency.
