MAX6431ORUS+

Overview

The MAX6431ORUS+ is a low-power, dual-level battery monitor manufactured by Analog Devices Inc./Maxim Integrated. It features internal hysteresis and provides two independent low-battery output indicators to signal three distinct battery states: good, weak, or empty. The device monitors single lithium-ion cells or multicell alkaline/NiCd/NiMH supplies. It operates within a temperature range of -40°C to +85°C and utilizes a compact 6-pin USON package.

Feature Summary

• Dual low-battery output indicators for comprehensive power status monitoring
• Internal hysteresis prevents output oscillation during voltage transitions
• Minimum timeout period ensures supply voltage stabilization before system activation

Applications

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

Procurement Notes

Verify the specific suffix ORUS against official datasheets to confirm the package type and temperature grade. Ensure compatibility with the required threshold voltages for the target application. Confirm RoHS compliance status as indicated in the manufacturer documentation.

Selection Notes

Select this component when dual-stage battery depletion signaling is required. It is suitable for systems needing distinct operational modes for normal, low-power, and disabled states based on voltage thresholds. Consider the USON package size for space-constrained designs.

Part Context

This part belongs to the MAX6427–MAX6438 family of single/dual-level battery monitors. These devices are designed to indicate battery conditions by asserting outputs when voltage drops below specified thresholds. The family supports various monitoring options for portable equipment.

Replacement Considerations

Other members of the MAX6427–MAX6438 family may serve as substitutes if pinout and threshold specifications match. Verify functional equivalence regarding dual-output configuration and hysteresis characteristics.
