Component

4-port PSEIEEE 802.3afIEEE 802.3atPoE controllerClass4+QFN-48I²C

TMI7604R is an integrated 4-port IEEE 802.3af/at PoE PSE controller for 44 V to 57 V systems, with internal FETs, PD detection/classification, I²C monitoring, and optional Class4+ operation.

Best for

  • Four-port IEEE 802.3af/at PSE designs
  • PoE switches and routers
  • Midspan and power-injector designs

Avoid if

  • A design requires a documented IEEE 802.3bt controller
  • The total power budget, thermal path, or software configuration cannot be validated

Check before use

  • PMAX resistor and aggregate power limit
  • Class4+ enable and two-event classification settings
  • Port current limits, protection timers, and thermal layout
