MAX1620EEE+

Overview

The MAX1620EEE+ is a digitally adjustable LCD bias supply IC from Analog Devices Inc./Maxim Integrated, housed in a 16-QSOP surface-mount package. It operates within a supply voltage range of 3V to 5.5V and supports an extended industrial temperature range of -40°C to +85°C. Designed for LCD display applications, this PMIC features a supply current of 150µA. The component is classified as Not Recommended for New Designs (NRND) by the manufacturer.

Feature Summary

• Digitally adjustable LCD bias generation
• Integrated power management for display panels

Applications

• LCD display systems
• Portable electronic devices with liquid crystal screens

Procurement Notes

Verify the Not Recommended for New Designs status before integration into new hardware. Confirm that the 16-QSOP package dimensions match existing PCB footprints. Ensure supply voltage requirements align with system rails between 3V and 5.5V. Check for available lifecycle alternatives if long-term production support is required.

Selection Notes

Select this component only for maintenance or legacy board revisions where the specific digital adjustment interface is already implemented. Evaluate pin compatibility with existing designs. Consider the limited future availability associated with NRND status when planning production volumes.

Part Context

This device belongs to the Maxim Integrated LCD bias supply family, designed to provide regulated voltages for liquid crystal displays. The EEE+ suffix indicates a lead-free, RoHS-compliant variant in a 16-SSOP/16-QSOP package. It serves as a specialized power management solution for portable electronics requiring precise LCD contrast control.
