Product Summary
The TPS2375PW-1 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-1 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-1 has 802.3af compliant UVLO limits, the TPS2377 has legacy UVLO limits. The applications of the TPS2375PW-1 include VoIP Phones, WLAN Access Points, Security Cameras, Internet Appliances, POS Terminals.
