PD81101 Datasheet | Microchip Technology

features , implemention of RPF macros required to perform line analysis, safe power feeding, and disconnection of ports in case of error, all with minimum external ponents. The PD81101 and PD81000 chipset is designed to ply with ETSI's TS 101 548 Metallic Detection Startup (MDSU) protocol and supports detection and classification prior to power-up, provides continuous protection from Error Line Conditions (ELC) prior to power-up and afterwards, in accordance with the standard. The RPF chipset provides real-time protection against overload, under-load, over-voltage, short-circuit, foreign DC voltage, and off-hook phone. This chipset allows the CPE host to receive telemetry data through I2C munication of RPF line status. The same munication can be used for software download and field upgrades. The PD81101 device operates from a wide supply voltage range (32 V- 60 V), with no need for additional power supply sources. This is a low-power dissipation device that uses internal MOSFET and sense resistor, and is available in a 56-pin, 8 mm × 8 mm QFN package. The PD81000 device is available in a 32-pin, 5 mm × 5 mm QFN package. The firmware supports detection and classification, RPF power-up requirements, monitor and control of RPF features , and implementation of RPF macros required to perform line analysis, safe power feeding, and disconnection of ports in case of an error. © 2020 Microchip Technology Inc.
