PD64012GH Datasheet | Microsemi

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 munication interface and a minimum of external ponents, 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 571m A 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. ..
