  1. 1Introduction
  2. 2Introduction to electric motor drives
  3. 3Understanding fault events in electric motor drives
  4. 4Achieving reliable detection and protection in electric motor drives
  5. 5Use case No. 1: Bidirectional in-phase overcurrent detection
  6. 6Use case No. 2: DC+ overcurrent detection
  7. 7Use case No. 3: DC– overcurrent or short-circuit detection
  8. 8Use case No. 4: DC-link (DC+ to DC–) overvoltage and undervoltage detection
  9. 9Use case No. 5: IGBT module overtemperature detection

7 Use case No. 3: DC– overcurrent or short-circuit detection

Similar to the details as explained in use case No. 2, you can also use the AMC23C11 to detect overcurrent on the DC– line. If you require both overcurrent and short-circuit detection, you can use the AMC23C14 to set the two threshold levels for overcurrent and short-circuit detection, respectively.
