PRODUCTION DATA
The VCC1 input power supply supports a wide voltage range from 3 V to 15 V and the VCC2 output supply supports a voltage range from 9.5 V to 33 V. 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 VCC2 and VEE2 output supplies for bipolar operation are 15 V and –8 V with respect to GND2 for IGBTs and 20 V and –5 V for SiC MOSFETs.
For operation with unipolar supply, the VCC2 supply is connected to 15 V with respect to VEE2 for IGBTs, and 20 V for SiC MOSFETs. The VEE2 supply is connected to 0 V.
