MAX6776XKC+T

Overview

The MAX6776XKC+T is a low-power, 1%-accurate battery monitor manufactured by Analog Devices Inc. under the Maxim Integrated brand. It is designed for monitoring single lithium-ion cells or multicell alkaline, NiCd, and NiMH power sources. The device features a fixed low-battery output with resistor-adjustable hysteresis to eliminate output chatter caused by input-voltage noise or battery terminal voltage recovery. It operates within a supply voltage range of 2.0V to 5.5V and is available in an ultra-small µDFN package measuring 1.0mm x 1.5mm.

Feature Summary

• Provides 1% accuracy for precise battery level monitoring
• Features adjustable hysteresis to prevent output chatter from noise or voltage recovery
• Optimized for low-power applications in portable devices

Applications

• Single lithium-ion cell monitoring
• Multicell alkaline battery stack supervision
• NiCd/NiMH power source management

Procurement Notes

Verify the specific suffix 'XKC' against official Analog Devices documentation to confirm pinout, hysteresis configuration, and package variant. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure RoHS compliance matches project requirements. Cross-reference the datasheet revision date to validate electrical characteristics before integration.

Selection Notes

Select this component when high accuracy is required for single-cell battery supervision in space-constrained designs. The adjustable hysteresis feature makes it suitable for noisy environments where stable low-battery signaling is critical. Compare against the broader MAX6775–MAX6781 family to ensure the fixed output configuration meets system logic requirements without additional external components.

Part Context

This part belongs to the MAX6775–MAX6781 series of low-power battery monitors. These devices are engineered for ultra-small form factors, utilizing µDFN and SC70 packages. The series supports both single and dual low-battery outputs, catering to various portable electronics that require reliable power management with minimal footprint and current consumption.

Replacement Considerations

Consider MAX6775XKC+T or MAX6777XKC+T from the same family if different output configurations are needed. Verify package compatibility and electrical specifications against the original design requirements before substitution.
