TPS2480 and TPS2481 Evaluation Module
This user’s guide describes the evaluation modules (EVM) for the TPS2480 and TPS2481. TPS2480 and
TPS2481 are positive-voltage, power-limiting, hot-swap controllers with a built-in I2C™ current monitor.
The TPS2480 operates in a latched fault manner whereas the TPS2481 operates in an automatic retry
manner.
