3 Description
The TPS23753A supports a number of input-voltage ORing options including highest voltage, external adapter preference, and Po E preference.
The Po E interface features an external detection signature pin that can also be used to disable the internal hotswap MOSFET. This allows the Po E function to be turned off. Classification can be programmed to any of the defined types with a single resistor.
The DC-DC controller features a...
