IEEE 802.3af POWER INTERFACE SWITCH FOR POWER OVER ETHERNET(PoE) POWERED DEVICES

Acting as an Interface between the power sourcing equipment (PSE) and the powered device (PD), the TPS2370 performs all detection, classification, inrush current limiting, and Switch FET control that is necessary for compliance with the IEEE 802.3af Standard. An internal 0.3- FET provides maximum power delivery. As an additional feature, the TPS2370 Interfaces with the enable/soft-start signal of a dc-to-dc converter, eliminating the need to have an accurate UVLO in the dc-to-dc converter. At low input voltages (1.8 V to 10 V), the TPS2370 draws less than 12 A, allowing accurate sensing of the external 24.9-k discovery resistor. At input voltages between 15 V and 20 V, an external resistor sets the level of current to be drawn during classification mode. TPS2370 is compatible with current as well as voltage measurement schemes for classification. Above 20-V input, the classification current is shut off, reducing internal power dissipation. The TPS2370 drives an internal low-side FET for control of the return side of the power path. The internal FET is turned on when the input voltage reaches 40 V and above. When the input voltage decreases, the FET remains on until the input voltage drops to below 30 V By Texas Instruments
