DS2756E+

Battery Management Overview

The DS2756E+ is a high-accuracy, stand-alone battery fuel gauge IC designed for single-cell lithium-ion and lithium-polymer batteries. It operates within a supply voltage range of 3 V to 4.5 V and supports a maximum output current of 4 mA. The device features a programmable suspend mode to minimize power consumption during idle states. It is housed in an 8-pin TSSOP package with dimensions of 4.4 x 3.1 x 0.95 mm and functions reliably across an operating temperature range from -40 °C to +85 °C.

Battery Management Feature Summary

• Provides high-accuracy state-of-charge monitoring for single-cell lithium-based battery packs
• Integrates a programmable suspend mode to reduce active current consumption during system idle periods
• Delivers precise coulomb counting and voltage measurement without requiring external microcontrollers

Battery Management Applications

• Portable consumer electronics such as mobile phones and PDAs
• Medical devices requiring accurate battery life estimation
• Industrial handheld instruments and sensors

Battery Management Procurement Notes

Verify the specific suffix and tape-and-reel availability when sourcing replacements, as packaging formats may differ between tube and reel configurations. Confirm that the component meets RoHS compliance standards required for your target market. Check for obsolescence notices or lifecycle status updates from Analog Devices to ensure long-term supply stability for production runs.

Battery Management Selection Notes

Select this component when designing systems that require precise remaining capacity tracking for single-cell Li-ion or Li-Po batteries. It is suitable for applications where low standby current is critical due to the integrated suspend feature. Ensure the design accommodates the 8-pin TSSOP footprint and operates within the specified -40 °C to +85 °C temperature envelope.

Battery Management Part Context

This part belongs to the Maxim Integrated (now Analog Devices) DS27xx series of battery management solutions. These components are widely used in portable electronics to replace simple voltage-based battery indicators with more accurate fuel gauging algorithms. The DS2756E+ specifically targets cost-sensitive applications needing reliable charge estimation without complex external processing.

Battery Management Replacement Considerations

DS2756E+T&R; and DS2756E TR are functionally equivalent variants differing primarily in packaging format.
