MAX16129AUAEBD+T

Overview

The MAX16129AUAEBD+T is a load dump and reverse voltage protection circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3V to 30V and draws a maximum supply current of 260µA. The device features an adjustable overvoltage threshold, with a specific limit of 15V for this variant, and provides an open-drain output. It includes a reset delay time of 150ms and functions reliably across an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides integrated protection against automotive load dump events and reverse voltage connections.
• Features an adjustable overvoltage detection threshold to accommodate various system requirements.
• Delivers an open-drain status output signal for monitoring protection events.

Applications

• Automotive electronic systems requiring load dump protection
• General-purpose power management circuits needing reverse voltage blocking
• Industrial equipment protected against transient voltage spikes

Procurement Notes

Verify the exact suffix and revision level when sourcing, as manufacturing changes may occur. Confirm RoHS compliance status directly with the supplier or official documentation. Check for end-of-life notifications or discontinuation notices prior to finalizing procurement plans. Ensure the package type matches the intended PCB footprint design constraints.

Selection Notes

Select this component when designing circuits that require dedicated hardware protection against high-voltage transients and polarity reversals. Consider the 260µA quiescent current impact on overall system power budgets. Verify that the adjustable threshold settings align with the sensitive downstream components' absolute maximum ratings.

Part Context

This part belongs to the MAX16128/MAX16129 family of supervisory circuits designed specifically for robust power management in harsh environments. It complements other Maxim Integrated PMIC solutions by offering specialized protection rather than general regulation. The uMAX/MSOP package allows for compact integration into space-constrained designs.
