Chipset eases transition to standard 90W PoE
Microchip is enabling both pre-standard and IEEE-compliant Powered Devices (PDs) to receive up to 90W of power without changing Power over Ethernet (PoE) switches or cabling.

The dual-pack IdealBridge MOSFET-based full-bridge rectifier device is used on the powered side of the PoE connection and protects PDs against reverse-polarity connections while cutting power, space and costs of delivering IEEE 802.3bt Type 4 Class 8 power.

Microchip’s IEEE 802.3bt-2018-compliant PSE chipset is available in volume quantities including the PD69208M, PD69204T4 and PD69208T4 PSE managers and PD69210 PoE controller. The PD70224 IdealBridge dual MOSFET-bridge rectifier is also available. Evaluation boards, design application notes, firmware, Graphical User Interface (GUI) software and the communication protocol are all available for download.

The injectors and midspans will be available in November 2019.
