PD70101 Datasheet Power Over Ethernet 802.3af/at Pd Controller

Manufacturer: Microsemi (now Microchip Technology)

Overview: PD70101 / PD70201 Datasheet Power Over Ethernet 802.3af/at PD Controller The PD70101 and PD70201 are integrated Powered Device Interface and PWM controllers for a DC-DC converter used in IEEE802.3af and IEEE802.3at applications. The PD70101 can be used for IEEE802.3af or IEEE802.3at Type 1 applications, while the PD70201 can also be used in IEEE802.3at Type 2 applications. A single PD70201 can be used in 4-pair applications which consumes up to 47.7W.

Key Features

  • designed to improve efficiency and reliability: Detection and Classification: The front end interface includes detection and classification circuitry. The detection signature resistor is disconnected upon completion of the detection phase. The system then begins the classification phase. Classification can be configured for Classes 0 to 4 via an external resistor. The PD70201 includes a two-events classification identification circuit which generates a flag to inform the PD.
