The TPS2375PW is an IEEE 802.3af PoE Powered Device Controller contains all of the features needed to develop an IEEE 802.3af compliant powered device (PD). The TPS2375 family is a second generation PDC (PD controller) featuring 100V ratings and a true open-drain, power-good function. In addition to the basic functions of detection, classification and undervoltage lockout (UVLO), this includes an adjustable inrush limiting feature. The TPS2375 has 802.3af compliant UVLO limits, this family specifications incorporate a voltage offset of 1.5V between its limits and the IEEE 802.3af specifications to accommodate the required input diode bridges used to make the PD polarity insensitive.
