6 Transient Protection

The TPS1HC100EVM provides several footprints and populated components used to mitigate transient power events such as ESD, surges, and inductive load turnoffs. These protection mechanisms are provided in addition to the integrated transient mitigation features of the TPS1HC100B-Q1. Refer to the TPS1HC100B-Q1 data sheet for more information about the internal protections that the device provides.

The TPS1HC100EVM provides the following transient protection features:

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