Description

The TPS23753A is a combined Power over Ethernet (PoE) powered device (PD) interface and current-mode dc/dc controller optimized specifically for isolated converter designs. The PoE implementation supports the IEEE 802.3-2005 (previously 802.3af) standard, 12.95 W (13 W) PD. The TPS23753A is compliant to IEEE 802.3at as a type 1 PD power interface.

The TPS23753A supports a number of input-voltage ORing options including highest voltage, external adapter preference, and PoE preference.

The PoE interface features an external detection signature pin that can also be used to disable the internal hotswap MOSFET. This allows the PoE function to be turned off. Classification can be programmed to any of the defined types with a single resistor.
