MAX6777LT+T

Overview

The MAX6777LT+T is a low-power, single-channel battery monitor manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1 V to 5.5 V and features an ultra-low quiescent current of 7 µA. The device provides accurate battery monitoring with 1% accuracy and supports alkaline, lithium-ion, nickel cadmium (NiCd), and nickel metal hydride (NiMH) battery types. Housed in a compact UDFN-6 surface-mount package, it functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides highly accurate single-cell battery voltage monitoring with 1% precision for various chemistries including Li-ion and NiMH.
• Features ultra-low power consumption with a quiescent current of only 7 µA to extend battery life in portable applications.
• Includes fixed or resistor-adjustable hysteresis on the low-battery output to eliminate signal chatter caused by input noise or terminal recovery.

Applications

• Monitoring single lithium-ion cells in mobile devices
• Power management for multi-cell alkaline or NiCd/NiMH battery packs
• Low-power consumer electronics requiring extended standby times

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm that the specific suffix LT corresponds to the intended package and thermal characteristics. Ensure compatibility with existing board layouts regarding the UDFN-6 footprint and soldering profiles before integration into production systems.

Selection Notes

Select this component when precise single-cell monitoring is required alongside minimal static power draw. Consider the UDFN-6 package constraints for space-limited designs. Evaluate the need for adjustable hysteresis to manage noise sensitivity in noisy environments compared to fixed threshold alternatives.
