Additional Details

The MAX44211 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 MAX44211 can be switched to implement all world standards, trading off improved linearity for increased quiescent current. The MAX44211 delivers a high 1.5A linear output current and provides peak-to-peak differential voltage swing of up to 36V. The MAX44211 features very low intermodulation and harmonic distortion ensuring they meet worldwide PLC standards.

The MAX44211 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 MAX44211 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 MAX44211 device is specified for operation from -40°C to +85°C.
