Overview: PD69101
1-Port PSE PoE Controller Datasheet
Introduction
Microchip's PD69101 device is a single-port, mixed-signal, and high-voltage Power over Ethernet (PoE) driver. It is utilized in Ethernet switches and enables the network devices to share power and data over the same cable. It enables detection of IEEE® 802.3af-2003 compliant powered devices (PDs) and IEEE 802.3at high-power devices, ensuring safe power feeding and disconnection of ports, with full digital control and a minimum of external components. A plug-and-play device, the PD69101 executes all real-time functions as specified in the IEEE 802.3af-2003 (AF) and IEEE 802.3at high-power (AT) standards, including load detection, AF and AT classification, and multiple classification attempts (MCA).
Integrating power, analog, and state-of-the-art logic, the PD69101 fits into a single 24-pin plastic QFN package. The chip includes built-in internal thermal protection, and two LEDs provide port state and port type (AF/AT) indication.
