PD64004AH is a four-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 PD64004AH has two possible working configurations: a low-cost implementation, supporting up to
571mA and a fully IEEE802.3at-ready one. Both maintain the PD64004A Enhanced mode features, for
extended functions and added flexibility with the presence of the PD63000G MCU.
