2.4 Transient Protection

There are several footprints and populated components used to mitigate transient power events such as ESD, surges, and inductive load turn-offs. The TPS482H85EVM provides solder on pads to populate a TVS diode on VBB (D1) to protect against upstream power events (currently not populated). These protection mechanisms are provided in addition to the integrated transient mitigation features of the TPS482H85-Q1. Refer to the TPS482H85-Q1 data sheet for more information about the internal protections that the device provides.

For voltage transients greater than 60V, disconnect the LDO from the TPS482H85-Q1 by removing the shunt connector from the J15 header to prevent damage to the LDO. Supply power to the TPS482H85-Q1's signals with separate power supplies using the test points for the respective signals.
