TPS23523EVM-863 Evaluation Module
This user’s guide describes the TPS23523 evaluation module (TPS23523EVM-863). The TPS23523EVM-
863 contains evaluation and reference circuitry for the TPS23523, which is a low-side
Hot Swap
and
ORing controller targeted at telecom applications. In addition, this EVM contains an INA226 to
demonstrate how telemetry can easily be added to this solution.
