MAX16126TCC+

Overview

The MAX16126TCC+ is a supervisory circuit designed for load dump and reverse voltage protection in automotive applications. It operates within a supply voltage range of 3V to 30V and features an adjustable overvoltage threshold starting at 1.2V. The device draws a typical supply current of 224µA and supports surface mount installation in a 12-WFQFN package. It functions reliably across an operating temperature range of -40°C to +125°C and holds AEC-Q100 qualification.

Feature Summary

• Provides robust protection against extreme input voltage conditions including overvoltage, reverse voltage, and transient high-voltage pulses.
• Features an open-drain output type with no manual reset or watchdog timer functionality.
• Includes power failure detection capabilities for enhanced system monitoring.

Applications

• Load dump protection circuits
• Reverse voltage protection systems
• Automotive power supply supervision

Procurement Notes

Verify the specific suffix TCC+ corresponds to the required 12-WFQN package and lead-free compliance. Confirm AEC-Q100 qualification status if automotive reliability is mandatory. Ensure the adjustable threshold configuration matches the target overvoltage protection level. Check for active status versus obsolete variants in the MAX16126 family.

Selection Notes

Select this component when designing circuits requiring protection against automotive load dumps and reverse polarity events. The adjustable threshold allows customization for specific system voltage tolerances. Consider the low supply current for battery-efficient designs. Verify that the open-drain output interface is compatible with the downstream microcontroller or logic inputs.
