MAX6430MRUS+T

Overview

The MAX6430MRUS+T is a low-power, dual-level battery monitor designed for tracking single or multicell power supplies. It features internal hysteresis and provides two distinct output indicators to signal three battery states: good, weak, or empty. The device operates within a temperature range of -40°C to +85°C and is housed in a surface-mount SOT143-4 package.

Feature Summary

• Dual-level output architecture enables precise monitoring of three distinct battery conditions including normal operation, low-power mode, and system disablement.
• Internal hysteresis prevents output oscillation during voltage transitions near threshold levels.
• Optimized for low-power consumption suitable for portable applications.

Applications

• Monitoring single lithium-ion cells
• Tracking multicell alkaline power supplies
• Monitoring NiCd/NiMH battery packs

Procurement Notes

Verify the specific suffix MRUS corresponds to the SOT143-4 package and tape-and-reel packaging configuration. Confirm the RoHS compliance status indicated by the '+' suffix. Ensure the operating temperature range meets the application requirements of -40°C to +85°C. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current production status and availability.

Selection Notes

Select this component when dual-threshold detection is required to manage system power modes based on battery health. It is suitable for designs needing to distinguish between weak and empty battery states without complex external circuitry. Consider the SOT143-4 package constraints for board space. Verify that the input voltage range covers the expected battery discharge curve.

Part Context

This device belongs to the MAX6427–MAX6438 family of low-power battery monitors. While other variants in this series offer single-level outputs (e.g., MAX6427), the MAX6430 specifically provides dual-level outputs for more granular battery state indication. The family shares common design principles regarding low quiescent current and internal hysteresis.

Replacement Considerations

Compatible substitutes within the same family include MAX6431MRUS+T and MAX6432MRUS+T, which also feature dual-level outputs. Single-level alternatives such as MAX6427MRUS+T may be used if only one threshold is required, though functional capabilities will differ.
