MAX6366PKA26+

Overview

The MAX6366PKA26+ 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 reset threshold voltage of 2.63V. The device provides an active-low, open-drain reset output with a typical reset delay time of 280ms. Key functional blocks include a watchdog timer, battery backup switch, and chip-enable gating. It consumes only 15µA of quiescent current and supports operation across an industrial temperature range from -40°C to +85°C in an SOT-23-8 package.

Feature Summary

• Integrates a watchdog timer for system fault recovery
• Includes battery backup functionality for seamless power transitions
• Features chip-enable gating for power-down control

Applications

• Portable electronic devices requiring low standby current
• Battery-powered embedded systems
• Industrial control units operating in harsh environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as availability may be limited. Ensure the specific suffix matches required pinout and electrical characteristics before integration into design files.

Selection Notes

Select this component when a single-supervisor solution with integrated watchdog and battery backup is required. Compare against similar parts in the MAX6366P series based on specific threshold voltage needs and output drive requirements. Consider the SOT-23-8 footprint constraints and thermal dissipation limits during PCB layout planning.

Part Context

This part belongs to the MAX6366P family of low-power supervisors designed for microprocessor applications. It consolidates multiple monitoring functions into a compact surface-mount package, reducing bill-of-materials count compared to discrete solutions. The Maxim Integrated portfolio emphasizes reliability and low power consumption for portable and industrial sectors.

Replacement Considerations

Check for MAX6366 variants with different threshold voltages or output types. Verify pin compatibility with existing designs if substituting with other packages in the same family.
