MAX6367LKA29+T

Overview

The MAX6367LKA29+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 a fixed threshold voltage of 2.9V for the monitored input. The device provides an active-low, open-drain reset output with a typical reset delay time of 280ms. It includes a battery backup switch for seamless power transition and chip-enable gating functionality. The component is housed in an SOT-23-8 package and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates a battery backup switch to maintain system state during primary power loss
• Includes chip-enable gating to control reset assertion based on enable signals
• Provides low quiescent current consumption suitable for battery-powered applications

Applications

• Microprocessor system supervision
• Battery-powered portable devices
• Embedded controller monitoring

Procurement Notes

Verify the specific suffix and tape-and-reel packaging details against the manufacturer's latest datasheet before ordering. Confirm that the AEC-Q100 qualification status meets your project requirements if automotive compliance is necessary. Check for any recent obsolescence notices or lifecycle changes directly from Analog Devices to ensure long-term availability.

Selection Notes

Select this part when a fixed 2.9V threshold is required for single-supervision applications. The inclusion of chip-enable gating distinguishes it from standard supervisors lacking this feature. Ensure the SOT-23-8 package fits your board layout constraints compared to other pin-count options in the MAX6367 family.

Part Context

This component belongs to the MAX6367P series of low-power supervisory circuits. It shares functional similarities with other members like the MAX6365 and MAX6368 but differs in specific features such as manual reset capabilities or watchdog timers found in adjacent model numbers.

Replacement Considerations

Consider the MAX6367LKA29+ without the reel suffix for cut-tape needs. Verify compatibility with MAX6367 variants offering different thresholds if the 2.9V setting is not strictly mandatory.
