Overview
The MAX16129UAAGA+ is a supervisory circuit designed for load dump and reverse voltage protection, manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 3V to 30V and functions reliably across an extended temperature range of -40°C to +125°C. The device is housed in an 8-pin µMAX package, suitable for surface-mount applications. It draws a maximum supply current of 260µA during operation.
Feature Summary
- Provides robust protection against damaging input-voltage transients such as load dumps.
- Detects and safeguards power supplies from reverse voltage conditions.
Applications
- Load dump protection
- Reverse voltage protection
Procurement Notes
Verify component authenticity through authorized channels due to limited availability status. Confirm package integrity and RoHS compliance before integration. Check for obsolescence notices or product change notifications (PCN) regarding manufacturing updates. Ensure design compatibility with existing system voltage thresholds and thermal requirements.
Selection Notes
Select this component when specific protection against high-voltage transients and polarity reversal is required for automotive or industrial power systems. Consider the 8-pin µMAX footprint for space-constrained designs. Evaluate the 260µA supply current against total system power budgets. Verify that the 3V to 30V operating range aligns with the target application's nominal supply voltage.
Part Context
This part belongs to the MAX16128/MAX16129 family of supervisory circuits focused on power management protection. It shares functional similarities with other devices in the series but is distinct in its specific pinout and protection thresholds tailored for µMAX packaging. The family addresses critical needs in protecting sensitive electronics from common power line anomalies.
Replacement Considerations
Public confirmed substitute: MAX16129AUAEBD+T. Note that the latter is marked as obsolete. Verify pin-to-pin compatibility and electrical specifications before substitution.
