MAX17073ETJ+

Overview

The MAX17073ETJ+ is a TFT-LCD step-up DC/DC converter manufactured by Analog Devices Inc. (Maxim Integrated). It utilizes a Boost topology to regulate voltage for display applications. The device operates within an input voltage range of 6V to 26V and provides precise battery capacity estimation, voltage monitoring, and temperature measurement functions. It is housed in a 32-TQFN (5x5) package with an exposed pad, designed for surface mount installation.

Feature Summary

• Integrates TFT-LCD step-up DC/DC conversion capabilities
• Provides precise battery capacity estimation functionality
• Includes built-in voltage monitoring and temperature measurement

Applications

• TFT-LCD power supply systems
• Battery-powered portable devices requiring capacity estimation
• Systems needing integrated voltage and temperature monitoring

Procurement Notes

Verify component status carefully as the MAX17073ETJ+ is listed as discontinued or limited supply in multiple sources. Confirm availability through authorized distributors or factory special orders. Ensure the specific suffix matches requirements, noting that packaging variations may exist. Cross-reference datasheets for updated electrical characteristics before integration into new designs.

Selection Notes

Select this component when a combined boost converter and fuel gauge solution is required for TFT-LCD applications. The integrated nature reduces bill of materials count by combining power management and monitoring. Consider the 32-TQFN footprint for layout constraints. Verify input voltage compatibility with the 6V-26V range and ensure thermal performance meets system requirements for the exposed pad package.

Part Context

This part belongs to the Maxim Integrated portfolio, now part of Analog Devices Inc. It falls under the category of switching regulators and PMICs. The MAX17073 series is specifically targeted at mobile and portable electronics requiring efficient power management alongside accurate state-of-charge tracking for LCD displays.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative components must be identified based on functional equivalence in boost conversion and fuel gauge integration.
