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.
