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.
Start your PoE PD power supply design using Microchip MPLAB® Analog Designer.
Additional Features
Designed to support IEEE 802.3af Type 1 applications
PD detection & programmable classification signature
Signature resistor disconnection after detection
Integrated 0.6Ω 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
