MAX8211CUA+

Supervisors Overview

The MAX8211CUA+ is a microprocessor voltage monitor manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.5 V to 16.5 V and features a threshold voltage of 1.19 V. The device provides an active low, open-drain output with a reset delay time of 1.5 ms. It consumes 15 uA of operating current and offers 3.5% accuracy. The component supports battery backup switching and power failure detection. It is housed in an SOIC-8 package and functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise monitoring of single input voltage with configurable thresholds
• Includes dedicated power failure detection circuitry for system protection
• Supports battery backup switching to maintain operation during primary power loss

Supervisors Applications

• Microprocessor supervisory circuits requiring voltage monitoring
• Battery-powered systems utilizing backup power switching
• Industrial equipment needing power failure detection

Supervisors Procurement Notes

Verify the specific suffix 'CUA+' against official Analog Devices documentation to confirm the commercial temperature grade and SOIC-8 packaging variant. Ensure compatibility with the required 1.19 V threshold and open-drain output configuration for your design. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated power failure detection is required. The 1.19 V threshold suits applications monitoring lower voltage rails or specific reference levels. The open-drain output allows flexible interfacing with various logic families. Consider the 15 uA quiescent current for battery-sensitive designs. Verify that the SOIC-8 package fits the available PCB footprint and thermal requirements.

Supervisors Part Context

This device belongs to the MAX8211 series of microprocessor voltage monitors from Analog Devices. It is designed to provide reliable supervision for digital systems. The series typically includes variants with different thresholds and packages. The MAX8211CUA+ represents a specific commercial-grade version optimized for general-purpose voltage monitoring tasks in embedded electronics.

Supervisors Replacement Considerations

Check for MAX8211CSA+ as a potential alternative if pinout and electrical specifications match exactly. Verify that any substitute maintains the same 1.19 V threshold and open-drain output type. Ensure the replacement package is compatible with the existing board layout.
