MAX16127TC/V+

Overview

The MAX16127TC/V+ is an automotive-grade voltage supervisory circuit designed for load-dump and reverse-voltage protection. It operates within a supply voltage range of 3V to 30V and supports an extended temperature range from -40°C to 125°C. The device features an adjustable threshold voltage, active low open-drain output, and consumes 224µA of supply current. Packaged in a 12-WFQFN exposed pad surface-mount format, it provides limiter-mode fault management for overvoltage and thermal shutdown conditions.

Feature Summary

• Provides dedicated load-dump and reverse-voltage protection for automotive systems
• Features limiter-mode fault management for overvoltage and thermal shutdown events
• Includes adjustable threshold voltage with active low open-drain output

Applications

• Automotive load dump protection
• Reverse-voltage protection circuits
• Overvoltage fault management systems

Procurement Notes

Verify availability status as the component may be subject to limited supply or factory special orders. Confirm AEC-Q100 qualification and TQFN-12 package details against official datasheets before procurement. Ensure compatibility with 3V to 30V operating ranges and -40°C to 125°C temperature specifications.

Selection Notes

Select this component for applications requiring robust automotive-grade protection against transient overvoltages and reverse polarity. The adjustable threshold allows customization for specific system requirements. Verify that the 224µA supply current meets power constraints and that the open-drain output interface aligns with downstream logic levels.

Part Context

This part belongs to the Maxim Integrated supervisory circuit family, specifically engineered for automotive environments. It complements related models like the MAX16126 by offering distinct limiter-mode fault management rather than switch-mode operation. The device is designed to ensure system reliability under harsh electrical conditions typical in vehicle power networks.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with MAX16126 series only if switch-mode operation is acceptable, noting functional differences in fault management modes.
