PD69208T4/PD69204T4/ PD69208M PoE PSE Manager Introduction Microchip s PD69208T4, PD69204T4, and PD69208M Power over Ethernet (PoE) manager ICs integrate power, analog, and state-of-the-art logic into a single 8 mm 8 mm, 56-pin, plastic QFN package. The device is used in conjunction with a Microchip PSE controller or an Ethernet switch processor from a supported third-party vendor to provide an IEEE 802.3af/at/bt or Power over HDBase (PoH) Power Sourcing Equipment (PSE) solution. Typical PoE Application The following figure shows the typical PoE application of Microchip Generation 6 devices.
