IP808AR is an 8-port PSE (Power Sourcing Equipment) controller IC for PoE (Power over Ethernet) systems. It integrates power, analog and logic circuits into a single chip, and can be used for Midspans and Endpoint PSE applications. IP808AR meets all IEEE 802.3AF-2003 requirements, such as multi-point resistor detection, PD classification, DC Disconnect, and Back-off for Midspans. It also meets all IEEE 802.3AT-2009 requirements, such as two-event classification and supply maximum 36W per port. IP808AR comprises internal temperature monitoring and thermal protection to protect against junction overheating. The 3.3V regulator is built-in to support external devices. Multiple IP808ARs can integrate to build an 8 x N ports PSE system, and I2 C bus uses to collect PD power status from each IP808AR to support global power managements. Management switch host has options to communicate IP808ARs via I2 C bus for PSE management activities. Optocouplers can be implemented to provide electrical isolations between the host and IP808ARs for signal communication.
