MAX6775LTA+T

Overview

The MAX6775LTA+T is a low-power, 1%-accurate battery monitor from the MAX6775 series. It operates within a supply voltage range of 1V to 5.5V and consumes only 3µA of battery current. The device features an open-drain or push-pull low-battery output with fixed or adjustable hysteresis to prevent output chatter. It guarantees valid logic states down to VBATT = 1V and is immune to short battery transients. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Provides 1% accuracy threshold specification over the full temperature range
• Features low 3µA battery current consumption for extended battery life
• Includes fixed or resistor-adjustable hysteresis to eliminate output chatter
• Guarantees valid low-battery-output logic state down to 1V input

Applications

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

Procurement Notes

Verify the specific suffix 'LTA' against the manufacturer's official part numbering system to confirm package type and tape/reel configuration. Confirm RoHS compliance status and check for obsolescence notices, as this component may be subject to limited availability or end-of-life restrictions.

Selection Notes

Select this component when high accuracy and ultra-low quiescent current are critical for portable applications. Ensure the required hysteresis configuration matches the design needs to handle input noise. Verify that the SC-70 or µDFN package dimensions fit the PCB layout constraints.
