PRODUCTION DATA
The input side power supply VCC can support a wide voltage range from 3 V to 5.5 V. The device supports both unipolar and bipolar power supply on the output side, with a wide range from 13 V to 33 V from VDD to VEE. The negative power supply with respect to switch source or emitter is usually adopted to avoid false turn on when the other switch in the phase leg is turned on. The negative voltage is especially important for SiC MOSFET due to its fast switching speed.
