SLUU224A May 2005 – March 2022 TPS40100
The EVM contains a power-good pin to provide the user with a “power ok” signal. This pin is pulled up through a resistor to the 5VBP pin of the TPS40100. If any of the following conditions occur, the power-good pin will pull low.
This pin can be monitored with an oscilloscope to observe its behavior. Please see Section 5.3.6.
