MAX16126TCC+T

Overview

The MAX16126TCC+T is a supervisory circuit designed for load dump and reverse-voltage protection. It operates within a supply voltage range of 3V to 30V and features an adjustable overvoltage threshold starting at 1.2V. The device consumes 224µA of supply current and functions reliably across a temperature range of -40°C to +125°C. Packaged in a TQFN-12 format, it includes power failure detection capabilities.

Feature Summary

• Provides robust protection against automotive load dump events and reverse voltage conditions
• Features an adjustable overvoltage threshold for flexible system configuration
• Includes integrated power failure detection functionality

Applications

• Automotive load dump protection circuits
• Reverse voltage protection systems
• Voltage supervision in harsh environments

Procurement Notes

Verify the specific suffix 'TCC' to ensure the correct package variant and threshold specifications are selected. Confirm AEC-Q100 qualification status if automotive compliance is required. Check current availability as stock levels may be restricted. Ensure the open-drain output type matches the downstream logic requirements.

Selection Notes

Select this component when designing systems requiring protection against transient high-voltage events up to 30V. The adjustable threshold allows customization for different input rail voltages. Consider the low supply current for battery-sensitive applications. Verify that the TQFN-12 package fits the available PCB footprint constraints.

Part Context

This part belongs to the MAX16126 series of supervisory circuits from Analog Devices/Maxim Integrated. The series focuses on protecting sensitive electronics from voltage anomalies common in industrial and automotive settings. The TCC suffix denotes a specific package and threshold configuration within this family.

Replacement Considerations

Direct substitutes include other variants within the MAX16126 series such as MAX16126TCA+T or MAX16126TCB+T, provided the package and threshold requirements align. Cross-reference with similar load-dump protectors from other manufacturers only if electrical parameters match exactly.
