Power Driver Modules FAQ

How is the overcurrent protection triggered?

Overcurrent detection is activated by connecting the ITRIP input to the IGBT current feedback. The comparator threshold is typically 0.5 V referenced to VSS ground.

What is the function of the RFE pin?

The RFE pin combines three functions: programmable fault clear time adjustment via an external RC network, fault output indication, and enable input functionality.

Can the low-side emitters be used for current measurement?

Yes, the low-side emitters (NU, NV, NW) are available for current measurements of each phase leg to facilitate precise control.
