MAX6776LTC+

Overview

The MAX6776LTC+ is a low-power, 1%-accurate battery monitor manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 0.8V to 5.5V and features a single low-battery output with fixed hysteresis to eliminate output chatter caused by input-voltage noise or terminal voltage recovery. The device is housed in an ultra-small µDFN package measuring 1.0mm x 1.5mm, suitable for space-constrained portable systems.

Feature Summary

• Provides 1% accuracy for precise battery level monitoring
• Features fixed hysteresis to prevent output chatter from voltage noise
• Operates on extremely low power consumption suitable for battery-powered devices

Applications

• Single lithium-ion cell monitoring
• Multicell alkaline power source supervision
• Small portable electronic systems
• NiCd/NiMH battery management

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations such as LTAT, LTBT, or LTT indicate different package types like SC70 or µDFN. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may be restricted due to lifecycle status. Ensure the selected variant matches the required physical footprint for PCB integration.

Selection Notes

Select this component when high accuracy and minimal board space are critical requirements. The fixed hysteresis feature simplifies design by removing the need for external components to stabilize the output signal. Consider the specific package option (µDFN vs. SC70) based on available layout area and thermal dissipation needs for the target application environment.

Part Context

This part belongs to the MAX6775–MAX6781 family of low-power battery monitors. These devices are designed for applications requiring reliable power management in compact form factors. The series supports both single and dual low-battery outputs, offering flexibility for various battery chemistries including Li+, alkaline, NiCd, and NiMH sources.

Replacement Considerations

Compatible substitutes include MAX6775, MAX6777, and MAX6778 from the same family. Verify pinout compatibility and package dimensions before substitution. Other variants in the series offer dual outputs or adjustable hysteresis if system requirements differ.
