Description

General part information

TPS2375-1 Series

These easy-to-use 8-pin integrated circuits contain all of the features needed to develop an IEEE 802.3af-compliant powered device (PD). The TPS2375-1 and TPS2377-1 are second generation PDCs (PD Controllers) featuring a 100-V ratings and true open-drain, power-good function. These devices are auto-retry versions of selected TPS2375 family members. Information on the TPS2375/6/7 devices can be found on the TPS2375/6/7 data sheet (SLVS525A).

In addition to the basic functions of detection, classification, and undervoltage lockout (UVLO), these controllers include an adjustable inrush limiting feature. The TPS2375-1 has 802.3af-compliant UVLO limits, and the TPS2377-1 has legacy UVLO limits.

The TPS2375 family specifications incorporate a voltage offset of 1.5 V between its limits and the IEEE 802.3af specifications to accommodate the required input diode bridges used to make the PD polarity insensitive.
