PD70201 802.3af/at PD Controller

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. These dev.

PD70201 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. C
