MAX17310G+

Overview

The MAX17310G+ is a high-accuracy, single-cell lithium-ion (Li+) battery fuel gauge manufactured by Analog Devices Inc./Maxim Integrated. It utilizes the company's patented AccuPak technology to provide precise State of Charge (SoC) and remaining capacity measurements. The device features an integrated 12-bit Analog-to-Digital Converter (ADC) for monitoring cell voltage and current. It supports I2C-compatible communication interfaces for system integration. Key operational parameters include a supply voltage range of 2.7V to 5.5V and an operating temperature range of -40°C to +85°C. The component is housed in a compact 10-pin TDFN package.

Feature Summary

• Implements AccuPak technology for enhanced coulomb counting accuracy and reduced calibration requirements.
• Provides real-time monitoring of battery state of charge, remaining capacity, and health status.
• Integrates a high-resolution ADC for simultaneous measurement of cell voltage and sense resistor current.
• Supports standard I2C/SMBus communication protocols for seamless host controller interface.

Applications

• Smartphones and mobile phones
• Tablets and portable media players
• Medical devices requiring precise power management
• Industrial handheld equipment

Procurement Notes

Verify the specific suffix 'G+' indicates lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm the package type matches the design requirements, as variations may exist within the product line. Ensure the source is an authorized distributor or the manufacturer directly to guarantee authenticity. Check for any recent obsolescence notices or lifecycle changes associated with this specific part number before finalizing procurement plans.

Selection Notes

Select the MAX17310G+ when high accuracy is required for single-cell Li+ batteries without frequent recalibration. It is suitable for applications where board space is limited due to its small footprint. Consider this component if the system requires detailed battery health reporting via standard digital interfaces. Evaluate the need for integrated protection features, as this device focuses on measurement rather than direct switching control.

Part Context

This component belongs to the Maxim Integrated fuel gauge portfolio, designed for portable electronics. It replaces older generation gauges that required more complex external circuitry or frequent user calibration. The AccuPak algorithm distinguishes it from basic coulomb counters by accounting for battery aging and varying discharge rates. It is part of a broader ecosystem of power management solutions for mobile devices.

Replacement Considerations

Consult official substitution guides for compatible alternatives such as the MAX17211 or MAX17048 series, depending on specific accuracy and interface needs. Verify pin compatibility and software register mapping if migrating from previous generations. Ensure that any substitute maintains the required I2C address configuration and interrupt signaling capabilities for the existing system design.
