MAX6776LTB+T

Overview

The MAX6776LTB+T is a low-power, single-channel battery monitor from the MAX6775–MAX6781 series. It provides accurate voltage monitoring for single lithium-ion cells or multi-cell alkaline, NiCd, and NiMH power sources. The device features a fixed low-battery output with adjustable hysteresis to eliminate output chatter caused by input noise or terminal voltage recovery. It operates within a supply voltage range of 1 V to 5.5 V and draws only 7 µA of quiescent current. Packaged in an ultra-small 6-pin µDFN (1.0 mm x 1.5 mm) format, it supports surface-mount installation and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Provides 1%-accurate battery voltage monitoring for single-cell Li-ion or multi-cell alkaline/NiCd/NiMH batteries.
• Features a low-battery output with fixed or resistor-adjustable hysteresis to prevent output chatter from input noise.
• Operates with ultra-low 7 µA supply current for extended battery life in portable applications.
• Available in a compact 6-µDFN package measuring 1.0 mm x 1.5 mm for space-constrained designs.

Applications

• Single-cell lithium-ion battery protection circuits
• Multi-cell alkaline battery pack monitoring
• NiCd and NiMH battery management systems
• Portable consumer electronics with limited board space

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Check for obsolescence notices or lifecycle changes as this part may have limited production runs. Ensure storage conditions meet moisture sensitivity level specifications to maintain reliability upon installation.

Selection Notes

Select the MAX6776LTB+T when precise single-channel battery monitoring is required with minimal power consumption. Choose this component over general supervisors if adjustable hysteresis is needed to handle noisy environments or voltage recovery effects. Consider the µDFN package size against available PCB real estate. Verify that the operating voltage range aligns with the target battery chemistry and system requirements.

Part Context

This component belongs to the MAX6775–MAX6781 family of low-power battery monitors designed by Maxim Integrated, now part of Analog Devices. The series offers both single and dual channel options in µDFN and SC70 packages. These devices are engineered for high accuracy and low standby current, making them suitable for modern portable devices where power efficiency and small form factors are critical design parameters.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate MAX6775LTB+T or MAX6777LTB+T for similar single-channel functionality within the same series, ensuring pin compatibility and parameter alignment before substitution.
