MAX6368LKA46+

Overview

The MAX6368LKA46+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features an adjustable overvoltage threshold. The device provides a push-pull active-low output with a fixed reset delay time of 280 ms. It includes battery backup functionality and chip-enable gating capabilities. The component is housed in an SOT-23-8 package and supports surface-mount installation.

Feature Summary

• Integrates battery backup switch for maintaining system state during power transitions
• Includes chip-enable gating signal for controlled power management sequencing
• Features adjustable overvoltage threshold detection for flexible monitoring requirements

Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing backup power supervision
• Embedded controllers utilizing chip-enable power gating

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing board layouts regarding the SOT-23-8 footprint. Confirm that the adjustable threshold settings meet the target application's voltage monitoring specifications before finalizing procurement decisions.

Selection Notes

Select this component when adjustable overvoltage protection is required alongside standard undervoltage supervision. The integrated battery backup feature makes it suitable for applications preserving critical data during power loss. Consider the 15 uA operating current for strict power budget constraints in portable designs.
