IP8008 is an 8 - channel 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.

IP8008 meets all IEEE 802.3bt - 2018 single - signature PD/dual - signature PD requirements, such as multi - point resistor detection, connection check, five - event PD classification, Autoclass, and DC Disconnect. It also meets all IEEE 802.3af - 2003, & 802.3at - 2009 requirements, such as two - event classification and supply maximum 48W per port.

IP8008 comprises internal temperature monitoring and thermal protection to protect against junction overheating. The 3.3V regulator is built - in to support internal system. Multiple IP8008 can integrate to build a maximum 8 × 16 ports PSE 802.3at, or 4 × 16 ports PSE 802.3bt system, and I²C bus uses to collect PD power status from each IP8008 to support global power managements.

Management switch host has options to communicate IP8008 via I²C bus non - isolation for PSE management activities, or optocouplers can be implemented to provide electrical isolations between the host and IP8008 for signal communication.
