DS2786G-C29+

Battery Management Overview

The DS2786G-C29+ is a stand-alone open-circuit voltage (OCV)-based fuel gauge designed for lithium-ion and lithium-polymer battery packs. It operates within a supply voltage range of 2.5 V to 4.5 V and provides an output voltage of 3.1 V with an output current capability of 4 mA. The device functions at a quiescent supply current of 50 uA and supports an operating temperature range from -40°C to +85°C. It is housed in a TDFN-10 surface-mount package.

Battery Management Feature Summary

• Provides stand-alone fuel gauge functionality based on open-circuit voltage measurement
• Supports lithium-ion and lithium-polymer battery chemistries
• Operates with low power consumption suitable for portable applications

Battery Management Applications

• Lithium-ion battery pack monitoring
• Lithium-polymer battery management systems
• Portable electronic devices requiring state-of-charge indication

Battery Management Procurement Notes

Verify the specific suffix C29 against official Analog Devices documentation to confirm exact ordering and packaging details. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure compatibility with host system interfaces before procurement.

Battery Management Selection Notes

Select this component when a simple, stand-alone OCV-based solution is required for single-cell lithium batteries. Consider the TDFN-10 package constraints and the specific 2.5 V to 4.5 V operating range. Evaluate if the 50 uA quiescent current meets system power budgets compared to more complex coulomb-counting alternatives.

Battery Management Part Context

This part belongs to the Maxim Integrated DS278x family of battery fuel gauges. These devices are designed for cost-sensitive applications where high precision is not critical. The family includes variants like the DS2781G and DS2784G, which offer similar standalone capabilities for different cell configurations.

Battery Management Replacement Considerations

Check for direct replacements such as the DS2781G+ or DS2784G+ if pinout and functional requirements align. Verify if updated models from the manufacturer offer improved accuracy or lower power consumption while maintaining interface compatibility.
