DESCRIPTION  
This 8-pin integrated circuit contains all of the features needed to implement an IEEE802.3at type-2 powered  
device (PD). The low 0.5 Ω internal switch resistance, combined with the enhanced thermal dissipation of the  
PowerPad™ package, enables this controller to continuously handle up to 0.85 A. The TPS2379 supports  
higher-power applications through the use of an external pass transistor. It also features a 100 V internal pass  
transistor, 140 mA inrush current, type-2 indication, auto-retry fault protection, and an open-drain power-good  
output.
