MAX16998BAUA/V+

Supervisors Overview

The MAX16998BAUA/V+ is an automotive-grade supervisory circuit featuring a watchdog timer with adjustable timeout delay. It operates within a wide input voltage range of 5V to 40V and maintains a low quiescent current of 18µA at +125°C. The device provides open-drain outputs for reset and enable signals, supporting TTL and CMOS compatibility. It includes power-fail detection and is housed in an 8-pin µMAX package.

Supervisors Feature Summary

• Integrated watchdog timer with capacitor-adjustable timeout periods
• High-voltage tolerance up to 40V for direct battery monitoring
• Low static current consumption suitable for energy-efficient systems
• Automotive qualification ensuring reliability under extreme temperatures

Supervisors Applications

• Microcontroller supervision in automotive electronic control units
• Fault detection and redundancy switching in industrial systems
• Monitoring downstream circuit integrity in high-voltage environments

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm AEC-Q100 certification compliance for automotive integration. Check datasheet revisions for parameter consistency. Validate package marking against official specifications. Ensure supply chain documentation meets quality standards.

Supervisors Selection Notes

Select this component for applications requiring robust fault detection in high-voltage automotive or industrial settings. Consider the adjustable watchdog timing flexibility for custom system requirements. Evaluate the low quiescent current benefit for power-sensitive designs. Assess the need for separate reset and enable signal outputs.
