MAX6429DHUR

Overview

The MAX6429DHUR+ is a low-power, single-level battery monitor with internal hysteresis from the Maxim Integrated MAX6427–MAX6438 family. It provides a low-battery output indicator to signal three battery conditions: good, weak, or empty. The device features factory-trimmed thresholds and operates in SOT-23-3 packages. It is designed for monitoring single lithium-ion cells or multicell alkaline/NiCd/NiMH power supplies.

Feature Summary

• Single low-battery output indicator for battery status
• Internal hysteresis for noise immunity
• Factory-trimmed threshold options
• Low current consumption

Applications

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

Procurement Notes

Verify the exact suffix 'DHUR' against official Maxim/Analog Devices documentation to confirm package type and temperature range. Ensure RoHS compliance matches project requirements. Confirm availability through authorized distributors as lead times may vary.

Selection Notes

Select this component when a single low-battery threshold is sufficient. Consider the MAX6430 series if dual thresholds are needed. Verify that the factory-trimmed voltage levels match the specific battery chemistry and cutoff requirements of the application.

Part Context

Part of the MAX6427–MAX6438 family of battery monitors. These devices offer single or dual low-battery outputs. The MAX6429 variant specifically provides a single output. The family supports various packaging options including SOT-23 and SOT-143.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6427–MAX6438 family with matching threshold voltages. Verify electrical specifications such as supply current and operating temperature range before substitution.
