Description

PD69108ILQ is an eight-port, mixed signal, high-voltage High Power over Ethernet (HPoE) power sourcing equipment (PSE) manager. The IC allows the detection of IEEE802.3at-2009 Type 1 and Type 2 powered devices, ensuring safe power feeding and removal over Ethernet ports. With full digital control via a serial communication interface and a minimum of external components, the IC integrates multi-port and highly populated Ethernet switches. The PD69108ILQ has built-in support for energy efficient PoE (EEPoE). The PD69108ILQ supports 2-event, 3-event and 6-event classification and up to 1000 mA (50 W at 50 VDC) per 2-pair channel, or 100 W per 4-pair channel per HDBaseT™ Type 3. It can be operated in Enhanced mode with the PD69100 MCU, in SmartFusion™ mode with a Microsemi SmartFusion device, or in Distributed PoE mode with Marvell ISSR, and is backwards compatible with PD69012, PD64012G, and PD64008G ICs for effortless transition into high power or EEPoE applications.
