PD69108 Eight-Port HPoE PSE Manager
PD69108 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 PD69108 has built-in support for energy efficient PoE (EEPoE).
The PD69108 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.
