Programmable microchip PD70100

analog

The PD70100 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 PD70100 is optimized for PD applications compliant with IEEE 802.3af Type 1 standards. 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 In addition, the devices have a discharge mechanism for a DC / DC input capacitor, ensuring quick re-detection capability in case the RJ-45 plug is disconnected and reconnected within a short time span. Product Features Designed to support IEEE 802.3af Type 1 applications PD detection & programmable classification signature Signature resistor disconnection after detection Integrated 0.6O isolating switch and inrush current limiter Less than 10 µA offset current during detection Single DC Voltage Input (37V – 57V) Wide operating temperature range: -40°C to 85°C On-chip thermal protection 12-pin, 3 × 4mm DFN MSL3, RoHS compliant
