MAX16914AUB/V+T

Overview

The MAX16914AUB/V+T is an overvoltage protection and battery reverse-polarity controller designed for automotive and industrial systems. It operates with a 4.5V to 19V input range and withstands transients up to +44V and -75V. The device controls two external pFETs to disconnect the load during faults, featuring adjustable overvoltage thresholds via a resistor divider. It offers 29µA quiescent current and 6µA shutdown current in a 10-pin µMAX package.

Feature Summary

• Provides ideal diode functionality for minimal forward voltage drop while preventing reverse current flow
• Detects power supply anomalies and actively disconnects loads to protect downstream circuitry
• Supports complete circuit shutdown to minimize static current consumption during inactive states

Applications

• Automotive systems requiring protection against load dump and voltage sags
• Industrial equipment exposed to transient high-voltage conditions
• Battery-operated systems needing reverse polarity protection

Procurement Notes

Verify the specific suffix 'V' against official Analog Devices documentation to confirm environmental compliance or variant specifications. Ensure the component matches the required 10-pin µMAX package dimensions and thermal characteristics for your design. Cross-reference the part number with authorized distributors to confirm availability status and authenticity before procurement.

Selection Notes

Select this controller when designing circuits that must endure severe electrical faults such as reverse battery connection or extreme voltage spikes. It is suitable for applications requiring low standby power consumption and precise overvoltage threshold management using external resistors. Consider the need for external pFET selection to optimize conduction losses and thermal performance.

Part Context

This component belongs to the MAX16914/MAX16915 family of supervisory circuits manufactured by Analog Devices/Maxim Integrated. These devices are specialized power management ICs focused on system protection rather than power conversion. They integrate sensing logic and control outputs to manage external switching elements efficiently.

Replacement Considerations

The MAX16915 serves as a functional alternative within the same series, differing primarily in its internal clamping behavior versus the MAX16914's high-impedance switching mode. Verify pin compatibility and threshold adjustment requirements when substituting.
