MAX16129UAEBD+

Overview

The MAX16129UAEBD+ 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 set at 15V. The device provides a reset delay time of 150ms and draws a typical operating supply current of 260µA. It utilizes an open-drain output type without manual reset or watchdog timer capabilities. The component is housed in an 8-uMAX package and supports surface-mount installation.

Feature Summary

• Provides integrated protection against automotive load-dump events and reverse voltage conditions
• Features an adjustable overvoltage threshold with a fixed 150ms reset delay for reliable system monitoring
• Operates with low power consumption suitable for battery-supplied applications

Applications

• Automotive electronic systems requiring load-dump protection
• Reverse voltage protection circuits
• General-purpose voltage supervisory applications

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as availability may vary by region. Confirm that the selected part matches the required 8-uMAX footprint and electrical specifications for your design. Check current lifecycle status, as this component may be subject to discontinuation notices from the manufacturer. Ensure compliance with RoHS standards if required for your project.

Selection Notes

Select this component when designing circuits that require dedicated hardware protection against high-voltage transients and polarity reversals. It is appropriate for systems operating between 3V and 30V where an open-drain reset signal is sufficient. Consider the 260µA quiescent current impact on total system power budget. Verify that the adjustable threshold meets the maximum input voltage requirements of the protected downstream components.
