PRODUCTION DATA
VEE2 operates with an input range of -12V to 0V, allowing a negative gate bias on the power FET during turn-off in both IGBT and SiC applications. This prevents the power FET from unintentionally turning on due to current inducted from the Miller effect. For operation with a unipolar supply, connect VEE2 to GND2. VEE2 is monitored with both an undervoltage and overvoltage comparator circuit to ensure valid operation. UV and OV conditions of VEE2 are recorded in FAULT2[UVLO3_FAULT] andFAULT2[OVLO3_FAULT], respectively.
