MAX6775LTA+

Overview

The MAX6775LTA+ is a low-power, single-cell battery monitor manufactured by Analog Devices Inc./Maxim Integrated. It provides 1%-accurate threshold detection for lithium-ion cells or multicell alkaline/NiCd/NiMH sources. The device features a fixed low-battery output with adjustable hysteresis to prevent output chatter caused by input noise or voltage recovery. It operates from -40°C to +85°C and draws only 3µA of battery current. The component is housed in an ultra-small 6-pin µDFN package measuring 1.0mm x 1.5mm.

Feature Summary

• Provides 1%-accurate threshold specification over the full operating temperature range
• Features low 3µA battery current consumption for extended operational life
• Includes open-drain or push-pull low-battery outputs with fixed or adjustable hysteresis

Applications

• Monitoring single lithium-ion (Li+) cells
• Monitoring multicell alkaline power sources
• Monitoring NiCd and NiMH battery packs

Procurement Notes

Verify the specific suffix 'LTA+' against official documentation to confirm package type and availability status. Confirm RoHS compliance and lead times directly with authorized distributors as supply conditions may vary. Ensure the selected variant matches the required output configuration and hysteresis settings for the target application design.

Selection Notes

Select this component when precise 1% accuracy is required for single-cell monitoring in space-constrained designs. The µDFN package suits applications needing minimal board area. Consider the 3µA quiescent current for battery-powered systems where longevity is critical. Verify that the fixed or adjustable hysteresis options meet the noise immunity requirements of the specific circuit environment.

Part Context

The MAX6775 series belongs to Maxim Integrated's family of low-power battery monitors designed for portable electronics. These devices are engineered to replace traditional discrete comparator circuits, offering higher accuracy and lower power consumption. The series supports various cell chemistries and provides reliable low-battery indication through integrated hysteresis mechanisms.
