PD64004A is a four-port, mixed-signal, high-voltage 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. 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 PD64004A has three possible working configurations: an Automatic stand-alone mode, for basic PoE
functions, the PoE+ Mode supporting legacy devices and autonomous operation with the PD33000G MCU and an
Enhanced mode, for extended functions and added flexibility with the PD63000G and PD83000G MCU’s.
