PD69101ILQ PoE Power Sourcing Equipment Controller

Microsemi’s IEEE 802.3at single-port PSE controller and manager is utilized in Ethernet switches

Image of Microsemi's PD69101ILQ PoE Power Sourcing Equipment ControllerThe PD69101ILQ from Microsemi Corporation is a single-port, mixed-signal, high-voltage PoE 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 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. Integrating power, analog, and state-of-the-art logic, the PD69101 device fits into a single 24-pin, plastic QFN package. As a plug-and-play device, the PD69101 executes all real-time functions as specified in the IEEE 802.3af-2003af (AF) and IEEE 802.3at 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 IEEE 802.3at-2009 standards. It can optionally detect legacy/pre-standard PD devices. The PD69101 also provides PD protection such as over-load, under-load, over-voltage, over-temperature, and short-circuiting. It supports supply voltages ranging from 44 V to 57 VDC with no need for additional power supply sources. The PD69101ILQ is ideal for communication, enterprise switches, routers, gateways, and IoT applications.
