PM8800A ST Power over Ethernet Controller | 16-TSSOP Exposed Pad | IEEE 802.3af, 25W

Product Overview

The PM8800A is a highly integrated Power over Ethernet (PoE) controller from STMicroelectronics, designed for Powered Devices (PDs) compliant with IEEE 802.3af standard. It integrates a high-efficiency DC-DC converter with a current-mode control architecture, enabling up to 25W output power. Housed in a compact 16-TSSOP package with exposed pad for enhanced thermal performance, the PM8800A simplifies PoE PD designs by reducing external component count and providing robust protection features.
