Description
General part information
TPS23757 Series
The TPS23757 is a combined Power over Ethernet (PoE) powered device (PD) interface and current-mode dc/dc controller optimized specifically for isolated converters. The PoE interface supports the IEEE 802.3at standard for a type 1 PD, which is equivalent to the 13W standard of IEEE 802.3-2008.
The TPS23757 supports a number of input voltage ORing options including highest voltage, external adapter preference, and PoE preference.
The TPS23757 has an output flag indicating if an external wall adapter is active when used in conjunction with ORing controls. The detection signature pin can also be used to force power from the PoE source off. Classification can be programmed to any of the defined types with a single resistor.
