MAX6779LTB+T

Overview

The MAX6779LTB+T is a low-power, dual-channel battery monitor from the MAX6775–MAX6781 series. It operates within a supply voltage range of 1 V to 5.5 V and consumes only 7 µA of quiescent current. The device provides two independent low-battery outputs with fixed or resistor-adjustable hysteresis to prevent output chatter caused by input-voltage noise or terminal voltage recovery. It supports monitoring single lithium-ion cells or multi-cell alkaline, NiCd, and NiMH power sources. The component is housed in an ultra-small 6-µDFN package (1.0 mm x 1.5 mm) and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual low-battery outputs for independent channel monitoring
• Resistor-adjustable hysteresis eliminates output chatter
• Ultra-low 7 µA quiescent current consumption
• Supports single Li-ion or multi-cell alkaline/NiCd/NiMH sources

Applications

• Single lithium-ion cell monitoring
• Multi-cell alkaline battery pack management
• NiCd and NiMH battery system supervision
• Portable electronic devices requiring low-power status indication

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status as specified in official documentation. Check for obsolescence notices or lifecycle changes prior to procurement. Ensure storage conditions meet moisture sensitivity level requirements. Validate part number suffixes against the latest manufacturer datasheet to confirm package and temperature grade specifications.

Selection Notes

Select this component when dual-channel battery status indication is required with minimal power impact. The adjustable hysteresis feature addresses noise sensitivity in noisy environments. Consider the 6-µDFN package size for space-constrained designs. Verify that the 1 V to 5.5 V operating range aligns with the target battery chemistry and system voltage levels. Evaluate thermal performance within the -40°C to +85°C industrial range.

Part Context

The MAX6779LTB+T belongs to the MAX6775–MAX6781 family of low-power battery monitors. This series offers single or dual output configurations in compact µDFN and SC70 packages. The family is designed for applications requiring accurate battery level detection with minimal standby current. The MAX6779 specifically provides dual outputs, distinguishing it from single-output variants like the MAX6775–MAX6778.
