High-Current Differential Line Driver
for Powerline Communications
General Description
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 overtemperature 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
