MAX6776XKB+T

Overview

The MAX6776XKB+T is a low-power, 1%-accurate battery monitor manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within an input voltage range of 0.8V to 5.5V and features a fixed output threshold of 2.3V. The device utilizes a µDFN-4 package (1.0mm x 1.5mm) for surface-mount installation. It supports a minimum operating temperature of -40°C and a maximum of +85°C. The component provides a single low-battery output with adjustable hysteresis to eliminate output chatter caused by input-voltage noise or terminal voltage recovery.

Feature Summary

• Provides 1% accuracy for precise battery level monitoring
• Features adjustable hysteresis to prevent output chatter from input noise
• Supports single lithium-ion cell or multi-cell alkaline/NiCd/NiMH power sources

Applications

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

Procurement Notes

Verify the specific suffix 'XKB' against official datasheets to confirm pinout and package dimensions, as variations exist within the MAX6775-MAX6781 family. Confirm RoHS compliance status directly with the manufacturer documentation. Check current supply availability through authorized distributors, as stock levels fluctuate. Ensure the selected variant matches the required output threshold and hysteresis configuration for the target application.

Selection Notes

Select this component when high accuracy and low quiescent current are critical for portable electronics. The adjustable hysteresis feature allows customization to handle noisy environments effectively. Consider the ultra-small footprint for space-constrained designs. Verify that the fixed threshold voltage aligns with the specific cutoff requirements of the battery chemistry being monitored.
