MAX6368LKA44

Overview

The MAX6368LKA44+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and consumes only 15 uA of quiescent current. The device monitors a single input channel with an adjustable overvoltage threshold and features a fixed reset delay time of 280 ms. It provides an active-low, push-pull output and includes battery backup functionality for seamless power transitions. The component supports chip enable gating and is housed in an SOT-23-8 surface-mount package, suitable for space-constrained designs.

Feature Summary

• Integrates battery backup switching to maintain system state during power transitions
• Supports chip enable gating for controlled supervision activation
• Delivers active-low push-pull reset output signals

Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing reliable power-fail detection
• Embedded controllers requiring supervised power-up sequences

Procurement Notes

Verify the exact suffix designation (+T) against official datasheets to confirm packaging type and RoHS compliance status. Confirm availability as distribution channels may list this part as discontinued or limited stock. Ensure the specific threshold voltage variant matches the design requirements before procurement.

Selection Notes

Select this component when a single-channel supervisor with battery backup and chip enable control is required. Compare against the MAX6365 series if manual reset inputs are needed instead. Verify that the adjustable overvoltage threshold meets the specific rail monitoring requirements of the target application.

Part Context

This part belongs to the MAX6368L family of uPower supervisors designed for low-voltage applications. It shares the SOT-23-8 footprint with other Maxim integrated circuits but offers specific supervision logic including battery backup and chip enable features distinct from standard reset generators.
