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

PD69101 Features

* Designed to detect and disable disconnected ports, utilizing DC disconnection methods as specified in the AF and IEEE802.3 af/at standards.

* Low-power device using an internal 0.34Ω MOSFET and an external 0.5Ω sense resistor.

* Optionally detects legacy/pre-standard PD de
