PD70200中文资料IEEE 802.3at PD front-end IC w/internal 0.6 Ohm FET数据手册Microchip规格书

描述 Description

The PD70200 device is a part of Microchip’s series of Power over Ethernet (PoE) Powered Devices (PDs). The device transmits integrated power and analog data in a single 12-pin package. It is used in PDs, thus enabling next generation network devices to share power and data over the same cable. Microchip’s new PD family offers a solution to any PD application compliant with IEEE 802.3af and IEEE 802.3at standards and 4-pairs extra power applications. The IC family’s components can be used in both indoor and outdoor applications. The device family meets all PD-side-standards such as:Detection classificationIntegrated isolation switch with inrush current limiter, and over-current protectionTwo-events classification recognition and AT flag generationIn addition, the devices have a discharge mechanism for a DC / DC input capacitor, ensuring quick redetection capability in case the RJ-45 plug is disconnected and reconnected within a short time span. The PD70200 IC design specifically supports IEEE 802.3at Type 2 standard, including two events classification detection that enables the PD to distinguish whether the connected power source equipment (PSE) is IEEE 802.3at or IEEE 802.3af based. The PD70200 IC is designed to support 4 pair applications for PDs that require higher power.Start your PoE PD power supply design using Microchip MPLAB® Analog Designer.
