Key Features

  • Quad-port PoE PSE controller managing IEEE 802.3at high-power Ethernet power delivery up to 30W per port simultaneously
  • Wide input voltage range of 21.5V to 57V accommodating both standard 48V PoE supplies and higher-voltage industrial power inputs
  • Integrated detection, classification, and current limiting functions reduce external component count for compact, reliable PoE switch designs

Applications

The TPS23841PAPR is designed for Power over Ethernet switches, access points, and IP surveillance camera hubs where centralized power management across multiple Ethernet ports is required. It handles IEEE 802.3at PoE classification and power delivery, simplifying the design of enterprise networking equipment and industrial PoE injectors. System designers use it in smart building automation, IP camera installations, and VoIP phone systems where cable-based power distribution eliminates the need for separate power adapters at each endpoint.
