MAX6366LKA44+

Overview

The MAX6366LKA44+ is a low-power voltage 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. The device provides a push-pull output capable of sourcing or sinking current, ensuring robust signal integrity. It includes a battery backup pin to maintain state during power transitions and offers a fixed reset delay time of 280ms. The component is housed in an SOT-23-8 package and supports surface-mount installation.

Feature Summary

• Push-pull output configuration for active high reset signaling
• Battery backup functionality to preserve system state
• Adjustable reset threshold voltage via external resistors
• Low quiescent current consumption for power efficiency

Applications

• Portable electronic devices requiring reliable power monitoring
• Embedded systems with microcontroller reset management
• Battery-powered equipment needing backup state retention
• Industrial control units operating in varying temperature ranges

Procurement Notes

Verify the specific revision status and availability through authorized distributors, as this component may be subject to discontinuation notices. Confirm that the SOT-23-8 package matches your PCB footprint requirements. Ensure compatibility with your system's voltage levels and reset timing constraints before finalizing procurement decisions.

Selection Notes

Choose this component when a push-pull output is required instead of open-drain configurations. It is suitable for applications needing adjustable reset thresholds rather than fixed values. Consider the battery backup feature if maintaining data integrity during power loss is critical. Evaluate the 280ms reset delay against your system's startup requirements.

Part Context

This part belongs to the MAX6366 series of uPower supervisors designed for low-voltage applications. It shares functional similarities with other Maxim Integrated supervisory circuits but distinguishes itself through its push-pull output and adjustable threshold capabilities. The series targets portable and battery-operated electronics where power management efficiency is paramount.

Replacement Considerations

Direct substitutes include other MAX6366 variants with compatible packages and electrical characteristics. Verify pinout compatibility and threshold adjustability when selecting alternatives. Cross-reference with MAX6367 or MAX6368 series parts only if their specific features align with your design requirements.
