Helping customers harness power delivered over a standard Ethernet cable, Texas Instruments announced a versatile IC controller and the industry's first Power-over-Ethernet plug-in power module that reduces design time and eases implementation of Ethernet-powered industrial and commercial devices such as WLAN access points, IP phones, security and point-of-sale systems. TI's TPS2375 controller builds upon the success of the TPS2370, introduced in 2003, to effectively manage discovery, classification and delivery of direct-current (DC) power to a powered device. The IC offers increased flexibility and performance as it manages the interface between the power source equipment (PSE) and a commercial or industrial powered device (PD), while providing necessary power management control and protection. The TPS2375 was created using TI's linear Bi-CMOS, silicon-on-insulator (LBC-SOI) process technology, which lets the controller withstand transients up to 100 V and operate over an industrial temperature range of -40C to 85C. The device also features 15-kV system-level electrostatic device (ESD) capability, adding unprecedented versatility to support extreme Power-over-Ethernet environments. In addition, the controller has an internal 0.6-ohm FET to minimize heat dissipation in the system. The controller further protects the powered device by implementing a 450-mA operating current limit, thermal shutdown and in-rush current limiting. The device utilizes a tiny external resistor to program in-rush current limit, enabling interoperability between a wide range of IEEE 802.3af-compliant and pre-802.3af "legacy" PSE systems.
