DESCRIPTION  
The 8-pin integrated circuit contains all of the features needed to develop a high power IEEE 802.3af style  
powered device (PD). The TPS2376-H offers a higher current limit and increased thermal dissipation capability  
over the TPS237X family of devices. The TPS2376-H implements a fully compliant PoE interface while  
permitting non-standard implementations that draw more power. A 26 W PD may be constructed when working  
from a 52 V minimum PSE over 100 m of CAT-5 cable. The TPS2376-H features a 100 V rating, 600 mA  
capability, adjustable inrush limiting, fault protection with auto-retry, and true open-drain power-good  
functionality.
