產品總覽
The TPS2379DDA is an IEEE 802.3at PoE high-power Powered Device Interface with external gate driver. It 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 140mA inrush current limit during startup. The low 0.5R internal switch resistance, combined with the enhanced thermal dissipation, enables this controller to continuously handle up to 0.85A. It integrates a low 0.5R internal switch to allow for up to 0.85A of continuous current through the PD during normal operation. The device supports higher-power applications through an external pass transistor. It contains several protection features such as thermal shutdown, current limit foldback and a robust 100V internal switch.
