MAX6368LKA46-T

Overview

The MAX6368LKA46-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features an adjustable overvoltage threshold. The device provides an active-low, push-pull output with a reset delay time of 280 ms. It includes a battery backup switch for maintaining system state during power transitions and utilizes a chip-enable signal for power management. The component is housed in an SOT-23-8 package and functions across a temperature range from -40 C to +85 C.

Feature Summary

• Integrates battery backup switching capability to preserve critical data during power loss events
• Features chip-enable gating functionality to minimize power consumption when the system is inactive
• Provides adjustable overvoltage detection thresholds to protect against excessive input voltage conditions

Applications

• Portable electronic devices requiring extended battery life through low-power supervision
• Embedded systems needing reliable voltage monitoring and reset generation
• Battery-operated equipment utilizing backup power sources for data retention

Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm that the specific suffix corresponds to the required adjustable threshold configuration. Check current availability status as distribution channels may indicate limited stock or discontinuation phases. Ensure compatibility with existing board layout constraints regarding the SOT-23-8 footprint.

Selection Notes

Select this part when adjustable overvoltage protection is required alongside standard undervoltage supervision. The inclusion of a manual reset input option in related variants should be considered if external reset control is needed. Evaluate the 15 uA operating current against system power budgets. Ensure the 280 ms reset delay meets the timing requirements of the target microcontroller or logic circuits.

Part Context

This component belongs to the MAX6368L series of uP supervisory ICs designed for low-power applications. It shares architectural similarities with the MAX6365L series but differs in specific feature sets such as the presence or absence of manual reset inputs. The family focuses on providing robust voltage monitoring solutions in compact packages suitable for space-constrained portable designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other MAX6368L variants only if pinout and functional specifications match exactly.
