MAX6806SA26

Supervisors Overview

The MAX6806SA26 is a precision voltage detector manufactured by Analog Devices Inc./Maxim Integrated, designed for accurate monitoring of power supplies in digital systems. It operates within a supply voltage range of 1V to 5.5V and features a factory-preset threshold of 2.6V with ±2% accuracy. The device provides an active-low, push-pull RESET output that remains valid down to 1V. Internal hysteresis ensures stable switching against noise. It is housed in an 8-pin SO package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise power supply monitoring with factory-set thresholds to eliminate external component adjustments
• Features internal hysteresis to ensure stable switching and prevent output oscillation during voltage transitions
• Delivers an active-low, push-pull reset signal that maintains validity even at low supply voltages

Supervisors Applications

• Monitoring power supplies in embedded digital systems
• Ensuring circuit reliability through automated voltage supervision
• Providing reset signals for microprocessors and logic circuits

Supervisors Procurement Notes

Verify the specific suffix 'SA26' corresponds to the 2.6V threshold and SO-8 package variant when sourcing. Confirm RoHS compliance status as indicated in official documentation. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability. Check for any recent product change notices or obsolescence announcements from Analog Devices.

Supervisors Selection Notes

Select this component when a fixed 2.6V threshold is required for system supervision. Choose the MAX6806 over MAX6807/8 variants if an active-low, push-pull output is necessary rather than open-drain or active-high configurations. Ensure the application environment falls within the specified -40°C to +85°C temperature range for guaranteed performance.

Supervisors Part Context

The MAX6806 belongs to the MAX6806/MAX6807/MAX6808 family of precision voltage detectors. This series offers multiple output types and packages to suit various design needs. The SA26 designation specifically indicates the 2.6V threshold version packaged in an 8-pin small outline package, distinguishing it from other threshold options like 4.6V or different package styles such as SOT23 or µMAX.

Supervisors Replacement Considerations

Direct substitutes include other members of the MAX6806/MAX6807/MAX6808 family with matching 2.6V thresholds and push-pull outputs, such as MAX6806SC26+ or MAX6806SE26+, provided the package footprint is compatible.
