Component

PoE PSE8-portIEEE 802.3afIEEE 802.3atClass4+QFN-48I²C

TMI7608R is an integrated eight-port IEEE 802.3af/at PoE PSE controller for switches, injectors, and midspan equipment. It includes power FETs, PD detection/classification, current protection, and I²C monitoring.

Best for

  • Eight-port PoE PSE switch designs
  • PoE midspans and power injectors
  • Systems requiring per-port power monitoring

Avoid if

  • A lower-voltage non-PoE power switch is required
  • Verified lifecycle or qualification information is mandatory but unavailable

Check before use

  • Confirm the total power budget and PMAX resistor selection.
  • Confirm Class4+ and two-event classification settings at reset.
  • Provide thermal copper and connect the exposed pad to AGND.
