MAX16129AUAEBD+

Overview

The MAX16129AUAEBD+ is a load dump and reverse voltage protection integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3V to 30V and draws a typical supply current of 260µA. The device features an adjustable overvoltage threshold set at 15V and provides a reset delay time of 150ms. Designed for surface mount installation, it utilizes an 8-uMAX/uSOP package with dimensions compatible with 8-TSSOP or 8-MSOP footprints. The component supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides dedicated protection against automotive load dump events and reverse voltage conditions
• Features an adjustable overvoltage threshold for flexible system configuration
• Includes a defined reset delay mechanism to ensure stable system recovery

Applications

• Automotive electronic systems requiring surge protection
• Avionics power distribution networks
• Industrial control equipment power supplies
• Telecommunications infrastructure power management

Procurement Notes

Verify the specific suffix 'A' in the part number to confirm the exact threshold and feature set, as variations exist within the MAX16129 family. Confirm that the 8-uMAX/uSOP package matches your PCB footprint requirements. Check current availability status as this component may be subject to limited supply or end-of-life restrictions depending on the manufacturing date code.

Selection Notes

Select this component when designing circuits that require robust protection against transient voltage spikes common in automotive environments. Ensure the input voltage range of 3V to 30V aligns with your system's nominal supply. Consider the 260µA quiescent current impact on overall power budget. Verify that the thermal dissipation capabilities of the 8-pin package are sufficient for your application's ambient temperature conditions.
