PD70200ILD-TR

PD70200ILD-TR is an IEEE® 802.3af/at PD front end IC. This 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. 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. Applications include power over ethernet powered devices, IEEE 802.3af/at 10/100/1000 BASE-T, 4-pair extra power applications, indoor and outdoor applications.
