PRODUCTION DATA
Since the input stage is an emulated diode, no power supply is needed at the input.
The output supply, VCC, supports a voltage range from 14V to 33V. For operation with bipolar supplies, the power device is turned off with a negative voltage on the gate with respect to the emitter or source. This configuration prevents the power device from unintentionally turning on because of current induced from the Miller effect. The typical values of the VCC and VEE output supplies for bipolar operation are 15V and -8V with respect to GND for IGBTs, and 20V and -5V for SiC MOSFETs.
For operation with unipolar supply, the VCC supply is connected to 15V with respect to GND for IGBTs, and 20V for SiC MOSFETs. The VEE supply is connected to 0V.
