MAX44211ETP+T

Overview

The MAX44211ETP+T is a high-current differential line driver designed for powerline communication (PLC) applications. It delivers a linear output current of up to 1.5A and provides a peak-to-peak differential voltage swing of 36V. The device operates from an analog supply range of +8V to +20V and a digital supply range of +2.7V to +5.5V. Quiescent current varies by mode, typically ranging from 1.9mA to 55mA at +25°C. It features programmable gains of 6x, 12x, 15x, or 18x via G1/G0 inputs. Integrated diagnostics include overtemperature shutdown at +160°C and warning at +150°C, alongside a programmable current limit set by an external resistor.

Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical parameters. Ensure that the specific ordering suffix matches the required package type and temperature range. Cross-reference the manufacturer's part number directly with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this driver when designing PLC interfaces requiring high peak currents to drive reactive loads. Evaluate the MODE input configuration to balance quiescent current consumption against linearity requirements for specific regional standards. Ensure adequate PCB copper area for the exposed pad to manage thermal dissipation during high-power transmission cycles.

FAQ

How is the output current limit configured?

The output current limit is set using an external resistor connected between the ILSET pin and AGND. The value determines the threshold at which the device limits current.

What is the function of the MODE input?

The MODE input selects the operating bias point. Leaving it unconnected minimizes quiescent current for CENELEC compliance, while pulling it high increases current to meet stricter ARIB and FCC linearity standards.

How does the device handle overtemperature conditions?

The device asserts STATUS1 low for a high-temperature warning at +150°C. If the junction temperature reaches +160°C, both status outputs go low, and the amplifier automatically shuts down until the temperature drops below the hysteresis threshold.
