MAX14916AAFM+

Overview

The MAX14916AAFM+ is an industrial octal high-side switch with diagnostics, manufactured by Analog Devices Inc. (Maxim Integrated). It features eight independent high-side outputs in a 48-FCQFN package. The device supports a load voltage range of 10V to 36V and operates on a supply voltage of 2.5V to 5.5V. Each channel provides a maximum output current of 1A, with a typical on-resistance of 120 milliohms. It utilizes SPI and parallel interfaces for control. The component includes comprehensive fault protection mechanisms such as fixed current limiting, open-load detection, overtemperature protection, overvoltage protection, and UVLO.

Feature Summary

• Integrates eight independent high-side power switches within a compact industrial-grade package.
• Provides advanced diagnostic capabilities including open-load detection and status flag reporting.
• Features robust fault protection against overcurrent, overtemperature, and overvoltage conditions.

Applications

• Industrial automation control systems
• Automotive body electronics modules
• General-purpose load switching in harsh environments

Procurement Notes

Verify the specific suffix 'AFM+' corresponds to the required tape-and-reel or tray packaging configuration as defined in the official datasheet. Confirm that the industrial temperature rating (-40°C to +125°C) meets the operational requirements of the target application. Ensure compatibility with the 48-FCQFN thermal pad soldering process during assembly.

Selection Notes

Select this component when eight isolated high-side channels are required with integrated diagnostic feedback. It is suitable for applications demanding high reliability under industrial conditions. Consider the 1A per-channel current limit and 120mΩ on-resistance for power dissipation calculations. Verify interface compatibility with SPI controllers if digital control is preferred over parallel inputs.

Part Context

The MAX14916 series belongs to Maxim Integrated's portfolio of intelligent power switches designed for automotive and industrial markets. These devices replace discrete MOSFET solutions, reducing board space and simplifying design. The AAFM+ variant specifically denotes the industrial temperature grade and the 48-lead FCQFN package type, ensuring performance stability across wide thermal ranges.

Replacement Considerations

The MAX14916AFM+ serves as a direct functional substitute within the same product family, offering identical pinout and diagnostic features. Users should verify if the specific suffix variation impacts packaging or minor electrical tolerances before substitution.
