MAX16129UADFD+T

Overview

The MAX16129UADFD+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 draws a typical supply current of 260µA. The device is housed in an 8-uMAX/8-MSOP package with dimensions of 3.00mm width. It supports an operating temperature range from -40°C to +125°C, ensuring reliability in demanding automotive and industrial environments.

Feature Summary

• Provides integrated protection against load-dump transients and reverse voltage conditions
• Features ultra-low supply current consumption for energy-efficient operation
• Designed for robust performance across extended industrial and automotive temperature ranges

Applications

• Automotive electronic systems requiring transient voltage protection
• Industrial automation equipment needing reverse polarity safeguarding
• Embedded systems utilizing PMIC architectures for power management

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix 'UADFD' matches the required 8-uMAX package variant. Check for end-of-life status as some listings indicate obsolescence. Ensure RoHS compliance documentation aligns with project requirements. Validate that the 260µA supply current meets system power budget constraints before finalizing procurement.

Selection Notes

Select this component when dedicated load-dump and reverse-voltage protection is required in a compact surface-mount form factor. The 3V–30V input range accommodates various automotive battery voltages. Consider the 8-pin uMAX package for space-constrained PCB layouts. Evaluate the 260µA quiescent current impact on overall system efficiency compared to alternative protection ICs.

Part Context

This part belongs to the MAX16129 family of supervisory circuits manufactured by Analog Devices Inc./Maxim Integrated. It falls under the PMIC (Power Management IC) category, specifically within load-dump and reverse-voltage protection subcategories. The device complements other Maxim supervisors like the MAX16128 series, offering specialized protection features rather than general monitoring functions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source data. Verify compatibility with existing protection circuits if cross-referencing with similar Maxim devices such as the MAX16128 series.
