MAX16126TCA/V+

Overview

The MAX16126TCA/V+ 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 draws a typical supply current of 224µA. The device functions reliably across an extended temperature range from -40°C to +125°C. It is housed in a compact 12-TQFN (3x3) surface-mount package with an exposed pad, facilitating integration into space-constrained power management systems requiring robust overvoltage and undervoltage monitoring.

Feature Summary

• Provides integrated protection against high-voltage load dump events common in automotive electrical systems
• Monitors supply voltage for both overvoltage and undervoltage conditions to ensure system integrity
• Includes reverse-voltage protection capabilities to prevent damage from incorrect polarity connections

Applications

• Automotive power distribution units
• Vehicle electronic control modules
• Load dump protection circuits in 12V/24V automotive networks

Procurement Notes

Verify the specific suffix '/V+' indicates automotive grade qualification and tape-and-reel packaging configuration. Confirm the 12-TQFN footprint matches your PCB layout requirements. Ensure compatibility with your system's voltage thresholds before finalizing procurement orders.

Selection Notes

Select this component when designing for harsh automotive environments requiring simultaneous load dump and reverse voltage protection. Consider the 224µA quiescent current impact on battery life. Verify that the 3V-30V input range aligns with your specific bus voltage specifications and noise margins.

Part Context

This part belongs to the Maxim Integrated MAX16126 family of supervisory circuits. It is functionally related to other variants like the MAX16126TCD and MAX16126TCB, which share similar protection features but may differ in pinout or specific threshold configurations. The EVKIT# variant serves as a development board for evaluating these protection functionalities.

Replacement Considerations

Direct substitutes include MAX16126TCA+T, MAX16126TCD+T, and MAX16126TCB+T. Verify pin compatibility and exact voltage thresholds before substitution, as suffix variations may indicate different packaging or minor parameter shifts.
