Product Summary
The TPS2375PW is an 802.3af PoE Powered device controller. The easy-to-use 8-pin integrated circuit contains all of the features needed to develop an IEEE 802.3af compliant powered device (PD). The TPS2375PW is a second generation PDC (PD Controller) featuring 100-V ratings and a true open-drain, power-good function. In addition to the basic functions of detection, classification and undervoltage lockout (UVLO), these controllers include an adjustable inrush limiting feature. The TPS2375PW has 802.3af compliant UVLO limits, the TPS2377 has legacy UVLO limits. The applications of the TPS2375PW include VoIP Phones, WLAN Access Points, Security Cameras, Internet Appliances, POS Terminals.
