Power Driver Modules FAQ

How does the module handle short-circuit protection?

Short-circuit protection is implemented only for the low-side IGBTs. The module detects overcurrent via the CSC pin and hard interrupts the gate signals, triggering a fault output pulse while turning off the affected IGBTs.

What is the purpose of the separated negative DC-link terminals?

The separate NU, NV, and NW terminals allow for direct connection to shunt resistors, enabling accurate three-phase current sensing without interference from the main DC-link ground path.

Can the VTS pin be used to automatically shut down the IGBTs?

No, the VTS pin provides a voltage output proportional to the internal LVIC temperature for monitoring purposes only. It does not automatically trigger an IGBT shutdown; external circuitry must interpret this signal to initiate protective actions.
