6 Transient Protection

The TPS1HC30EVM provides several footprints and populated components used to mitigate transient power events such as ESD, surges, and inductive load turn-offs. These protection mechanisms are provided in addition to the integrated transient mitigation features of the TPS1HC30-Q1. Refer to the TPS1HC30-Q1 data sheet for more information about the internal protections that the device provides.

The TPS1HC30EVM provides the following transient protection features:

  • Input TVS diode on VS (D2) to protect against upstream power events (not populated)
  • Optional external inductive load turn-off diode footprints on D3 to provide a mechanism to discharge an inductive load if the internal clamp is not adequate (not populated)
