ESD

The TPS23754 device has been tested to EN61000-4-2 using a power supply based on Figure 1. The levels

used were 8-kV contact discharge and 15-kV air discharge. Surges were applied between the PoE input and the

DC output, between the adapter input and the DC output, between the adapter and the PoE inputs, and to the

DC output with respect to earth. Tests were done both powered and unpowered. No TPS23754 device failures

were observed and operation was continuous. See Figure 29 for additional protection for some test

configurations.

ESD requirements for a unit that incorporates the TPS23754 have a much broader scope and operational

implications than are used in TI’s testing. Unit-level requirements should not be confused with reference design

testing that only validates the ruggedness of the TPS23754.

Layout

Printed circuit board layout recommendations are provided in the evaluation module (EVM) documentation

available for these devices.
