PD70101 Datasheet 802.3af/at Pd Controller

Manufacturer: Microchip Technology

Overview: PD70101 and PD70201 PoE IEEE® 802.3af/at PD Controller Introduction The PD70101 and PD70201 devices are integrated Powered Device (PD) interface and PWM controllers for a DC-DC converter used in IEEE® 802.3af and IEEE® 802.3at applications. The PD70101 device can be used for IEEE 802.3af or IEEE 802.3at Type 1 applications, while the PD70201 device can also be used in IEEE 802.3at Type 2 applications. A single PD70201 device can be used in 4-pair applications that consume up to 47.7 W.

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 applicatio.
