Dallas—Texas Instruments says its 26-watt powered device (PD) controller for power-over-Ethernet (PoE) applications, the TPS2376-H, is the first for the next wave of higher-powered systems such as IP surveillance cameras and phones.
The TPS2376-H eases powered device startup capability with adjustable in-rush current limiting circuitry and an auto-retry feature, which provides automatic start-up on fault. The controller includes several additional protection and low-noise features, such as 15-kV system-level electrostatic discharge (ESD) capability, adjustable under-voltage lockout, and power-good reporting (open-drain output).
The TPS2376-H can also operate at 24 volts, versus from traditional 52-volt power source equipment (PSE), to support emerging Ethernet-powered medical and industrial equipment.
