TEXAS INSTRUMENTS INTRODUCES HIGH-POWER POE MANAGER FOR MULTI-PORT SYSTEMS

Texas Instruments Incorporated has introduced the industry's first fully integrated Power over Ethernet (PoE) management device that allows multi-port enterprise systems to deliver up to 25 watts of power over a standard Ethernet cable. Supporting operation at -40 to +125 C, the power source equipment (PSE) manager enables commercial, industrial, medical and military applications to manage Ethernet-powered devices using nearly twice the power as previous IEEE 802.3af-compliant systems.

25-W PSE Manager with Wide Input Voltage Capability Simplifies Power Source Equipment Design in Industrial Applications

TI's TPS23841 quad-port PoE integrated circuit (IC) provides power management control and protection, while safely delivering up to 665 mA per port from input voltage levels of 21.5 V to 57 V. The device's extremely wide input voltage capability allows designers to support emerging Ethernet-powered 24 V medical and industrial applications.

The TPS23841 simplifies PoE design by integrating several key components onto a single chip, including integrated switches and sense resistors and four individual 15-bit analog-to-digital (A/D) converters.
