MAX44211

High-Current Diﬀerential Line Driver

for Powerline Communications

General Description

Beneﬁts and Features

● Meets Stringent ARIB, FCC, and CENELEC Linearity

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.

Specifications for Out-of-Band Emissions

• Output Drives Current Linearly Up to 1.5A Peak

Into a Reactive Load for PLC Applications

● Output Voltage Swings to Within 0.5V of AVDD or

AGND (36V

Range

Differential) for Widest Dynamic

P-P

● Wide Power-Supply Range Addresses Multiple

Standards:

• +8V to +20V for Analog Supply

• +2.7V to +5.5V for Digital Supply

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.

● Programmable Output Current Limit via External

Resistor Provides Flexibility

● Programmable Gain (6x, 12x, 15x, or 18x) via Gain

Inputs Provides Multistandard Usage

● Status Logic Outputs Provide Improved Diagnostics

• Overtemperature Shutdown Active

• High-Temperature Warning Active

• Overcurrent Active

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.

• Normal Operation

The MAX44211 device is specified for operation from

-40°C to +85°C.
