PD81101
Description
Microchip's PD81101 Reverse Power Feeding (RPF) manager is a mixed-signal, high-voltage IC, which integrates power, analog, and logic into a single 56-pin, plastic QFN package. It allows Customer Premises Equipment (CPE) devices and Distribution Point Units (DPU) to share and deliver power and data over the same cable.
Key Features
- DPU detection and classification in the presence of MELT signatures, according to ETSI TS 101
- Foreign DC voltage detection
- Off-Hook phone detection and line disconnection
- Support for error lineconditions
- I2C munication with CPE host
- Supports signaling indication to DPU through RPF voltage modulation (DGL/ACM/BAT)
- PD81000-programmable I2C address
- UDL/OVL indication andline-disconnection
- Single DC voltage input (32 V to 60 V)
- Input voltage out-of-range protection
