ZHCSA47E July 2012 – January 2018 TPS23751 , TPS23752
PRODUCTION DATA.
The TPS23751 and TPS23572 devices have a PoE that contains all of the features needed to implement an IEEE802.3at type-2 powered device (PD) such as Detection, Classification, Type 2 Hardware Classification, and 140-mA inrush current mode DC-DC controller optimized specifically for isolated converters.
The TPS23751 and TPS23752 devices integrate a low 0.5-Ω internal switch to allow for up to 0.85 A of continuous current through the PD during normal operation.
The TPS23751 and TPS23752 devices contain several protection features such as thermal shutdown, current limit foldback, and a robust 100-V internal switch.
