SI3462 Description
The Si3462 is a single-port power management controller for IEEE 802.3atpliant Power Sourcing Equipment (PSE). The Si3462 can be powered from a 50 V input using a shunt regulator, or, to save power, it can be powered from 50 V and 3.3 V power supplies. The IEEE-required Powered Device (PD) detection.
