PD64012GH

12-PORT HPoE PSE MANAGER

DESCRIPTION

PD64012GH is a twelve-port, mixed-signal, high-voltage High Power over Ethernet PSE Manager. The IC

allows the detection of IEEE 802.3af-2003 powered devices, ensuring safe power feeding and removal

over Ethernet ports. It also supports pre-standard IEEE802.3at devices consuming up to 59.5W. With full

digital control via a serial communication interface and a minimum of external components, the IC

integrates in multi-port and highly populated Ethernet switches.

The PD64012GH has two possible working configurations: a low-cost implementation, supporting up to

571mA and a fully IEEE802.3at-ready one. Both maintain the PD64012G Enhanced mode features, for

extended functions and added flexibility with the presence of the PD63000G MCU.
