Overview

The MAX44211ETP+ is a low-distortion line driver customized for powerline communication (PLC) applications where high output current is needed to drive the isolation and coupling transformer under varying load conditions. The MAX44211ETP+ can be switched to implement all world standards, trading off improved linearity for increased quiescent current. The MAX44211ETP+ delivers a high 1.5A linear output current and provides peak-to-peak differential voltage swing of up to 36V. The MAX44211ETP+ features very low intermodulation and harmonic distortion ensuring they meet worldwide PLC standards. The MAX44211ETP+ features advanced diagnostics for temperature and output current monitoring. There are high temperature warning and over temperature shutdown functions. There is also a programmable current limit. The status of these diagnostics are indicated via two open-drain status outputs. The MAX44211ETP+ is designed to interface to powerlines that have wide ranging and variable loads and drive signals within the 9kHz to 500kHz frequency band. This device operates from a single supply and is available in a 4mm x 4mm, 20-pin TQFN package. The MAX44211ETP+ device is specified for operation from -40°C to +85°C.
