6.3.1 Power Supplies

The input-side power supply VCC can support a wide voltage range from 3 V to 5.5 V to support both 3.3-V and 5-V controller signaling.

The output-side power supply, VDD to VEE, can support a wide range up to 30 V. The minimum VDD to VEE voltage will depend on the VDD UVLO variant being used. The device can support either unipolar or bipolar supplies. The negative power supply, VEE, with respect to source or emitter, COM, is usually adopted to avoid false turn on when the other switch in the phase leg is turned on. Negative voltage is important for SiC MOSFETs due to their fast switching speeds, as well as for IGBTs when not using an active Miller clamp. VDD is monitored by undervoltage comparators to enure valid operation. See Section 6.3.2 for more information about the VDD undervoltage lockout protections.
