MAX6367LKA46+

Overview

The MAX6367LKA46+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and features an adjustable reset threshold voltage, specifically set at 4.63V for this suffix variant. The device provides a push-pull active-low reset output with a typical timeout delay of 140ms. It incorporates battery backup switching functionality to maintain data integrity during power transitions. The component is housed in an SOT-23-8 surface-mount package and supports operation across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates battery backup switching to seamlessly transfer load between main and backup power sources.

Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing reliable power-fail detection
• Data logging equipment with non-volatile memory retention

Procurement Notes

Verify the exact suffix 'LKA46' to confirm the 4.63V threshold voltage setting, as variations exist within the MAX6367 family. Confirm current availability status, as distribution channels may list limited stock or obsolete status. Ensure compatibility with the target system's voltage levels and thermal requirements before finalizing procurement decisions.

Selection Notes

Select this component when a precise 4.63V supervision threshold is required alongside battery backup capabilities. Compare against other MAX6367 variants with different voltage suffixes if the system operating voltage differs. Consider the SOT-23-8 footprint constraints and verify that the low quiescent current meets the specific power budget of the application.

Part Context

This part belongs to the MAX6365/MAX6366/MAX6367 series of low-power supervisors. These components are designed for portable applications where minimizing current consumption is critical. The MAX6367 variant specifically adds battery backup switching, distinguishing it from the basic supervisor functions of the MAX6365 and MAX6366 models.

Replacement Considerations

Check for MAX6367LKA46+T equivalents with identical threshold voltages. Verify pinout compatibility with SOT-23-8 packages. Ensure replacement parts support the same battery backup switching feature and operate within the required temperature range.
