EVALUATION KIT AVAILABLE MAX44211 High-Current Differential Line Driver for Powerline Communications General Description Benefits and Features The MAX44211 is a low-distortion line driver customized Meets Stringent ARIB, FCC, and CENELEC Linearity for powerline communication (PLC) applications where Specifications for Out-of-Band Emissions high output current is needed to drive the isolation and Output Drives Current Linearly Up to 1.5A Peak coupling transformer under varying load conditions. The Into a Reactive Load for PLC Applications MAX44211 can be switched to implement all world Output Voltage Swings to Within 0.5V of AVDD or standards, trading off improved linearity for increased AGND (36V Differential) for Widest Dynamic P-P quiescent current. The MAX44211 delivers a high 1.5A Range linear output current and provides peak-to-peak differential Wide Power-Supply Range Addresses Multiple voltage swing of up to 36V. The MAX44211 features very Standards: low intermodulation and harmonic distortion ensuring they +8V to +20V for Analog Supply meet worldwide PLC standards. +2.7V to +5.5V for Digital Supply The MAX44211 features advanced diagnostics for Programmable Output Current Limit via External temperature and output current monitoring. There are Resistor Provides Flexibility high temperature warning and overtemperature shutdown Programmable Gain (6x, 12x, 15x, or 18x) via Gain functions. There is also a programmable current limit. The status of these diagnostics are indicated via two open- Inputs Provides Multistandard Usage drain status outputs. Status Logic Outputs Provide Improved Diagnostics Overtemperature Shutdown Active The MAX44211 is designed to interface to powerlines that have wide ranging and variable loads and drive signals High-Temperature Warning Active Overcurrent Active within the 9kHz to 500kHz frequency band. This device operates from a single supply and is available in a 4mm x Normal Operation 4mm, 20-pin TQFN package. The MAX44211 device is specified for operation from -40C to +85C.
