MICROCHIP PD70200ILD-TR

The PD70100 and PD70200 devices transmit integrated power and analog data in a single 12-pin package. They are used in Powered Devices (PDs), thus enabling next generation network devices to share power and data over the same cable. Microchip’s 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 - Classification Integrated isolation switch with inrush current limiter, and over-current protection Two-events classification recognition and AT flag generation (PD70200 only) In 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. PD70200 IC design specifically supports IEEE 802.3at 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. PD70100/PD70200 IC provides IEEE 802.3af/at compliant PD Front-End functions including Detection, Physical Layer Classification, Two-Events Classification (PD70200 only), Auxiliary Voltage Output, Power Good, Soft Start Current Limiting, Over-Current Protection, and Bulk Capacitor Discharge.
