MAX8212CSA

Supervisors Overview

The MAX8212CSA+ is a microprocessor voltage monitor featuring programmable voltage detection for a single input. It operates within a supply voltage range of 2 V to 16.5 V and draws 15 uA of quiescent current. The device provides an active low, open-drain output with a 3 ms reset delay time. It includes battery backup switching capabilities and power failure detection. Accuracy is specified at 3.5%, with overvoltage and undervoltage thresholds defined by the specific variant configuration.

Supervisors Feature Summary

• Provides programmable voltage detection for monitoring single-supply systems
• Features battery backup switching to maintain system integrity during power transitions
• Includes power failure detection logic for reliable operation

Supervisors Applications

• Microprocessor voltage supervision in embedded systems
• Battery-powered devices requiring backup switching
• Power management circuits needing programmable threshold monitoring

Supervisors Procurement Notes

Verify the exact suffix (e.g., CSA+) against the datasheet to confirm package type and temperature range. Confirm RoHS compliance status as it varies by manufacturing batch. Check for obsolescence notices or limited availability indicators from authorized distributors before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with programmable thresholds is required. Ensure the operating supply voltage range of 2 V to 16.5 V matches the system design. Consider the 15 uA quiescent current for low-power applications and verify that the open-drain output interface is compatible with the downstream logic.

Supervisors Part Context

The MAX8212 belongs to the Maxim Integrated supervisory circuit family designed for microprocessor systems. It offers precise voltage monitoring with programmable detection levels. The series supports various packages including SOIC and PDIP, catering to different board space and thermal requirements in industrial and consumer electronics.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX8212 series such as MAX8212EPA+ or MAX8212MJA. Verify that substitute parts maintain the same voltage range, accuracy, and output configuration.
