Introduction

KEY FEATURES

Microsemi's PD69101 is a single port, mixed-signal, high-voltage Power over Ethernet driver. The device is utilized in Ethernet switches and enables network devices to share power and data over the same cable. It enables detection of IEEE802.3af-2003 compliant PDs Powered Devices and IEEE802.3at High Power Devices, thus, ensuring safe power feeding and disconnection of ports with full digital control and a minimum of external components. Integrating power, analog and state of the art logic, the PD69101 device fits into a single 24-pin, plastic QFN package.

A “plug and play” device, the PD69101 executes all real time functions as specified in the IEEE802.3af-2003 “AF” and IEEE802.3at High Power “AT” standards, including load detection, “AF” and “AT” classification, and using Multiple Classification Attempts MCA .

The PD69101 :
• Is designed to detect and disable disconnected ports, utilizing DC disconnection methods, as specified in the IEEE 802.3af-2003 and IEEE802.3ar-2009 standards.
• Can optionally detect legacy/pre-standard PD devices.
• Provides PD protection such as over-load, under-load, over-voltage, over-temperature and short-circuiting.
• Supports supply voltages ranging from 44 V to 57 VDC with no need for additional power supply sources.
• Is a low power device using an internal MOSFET and an external sense resistor.

The chip includes built-in internal thermal protection.

Two LEDs provide port state's indication and port type AF/AT .
