MAX14916AFM+

Overview

The MAX14916AFM+ is an industrial octal high-side driver featuring eight independent channels. It operates with a supply voltage range of 2.5V to 5.5V and supports load voltages from 10V to 36V. The device provides a typical on-resistance of 120mΩ per channel and delivers up to 1.67A output current. It utilizes SPI or parallel interfaces for control. Key protection features include fixed current limiting, open-load detection, over-temperature shutdown, and under-voltage lockout (UVLO). The component is housed in a 48-FCQFN package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Octal high-side switch configuration with integrated state flags
• Comprehensive fault protection including current limiting and thermal shutdown
• Open-load detection capability for diagnostic monitoring
• Industrial-grade operation across extended temperature ranges

Applications

• Industrial power distribution systems
• Motor control applications requiring high-side switching
• Automotive electronic control units
• Load management in harsh environment electronics

Procurement Notes

Verify the specific suffix 'AFM+' against official Analog Devices documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with SPI or parallel interface requirements for your system design. Confirm that the 48-FCQFN footprint matches your PCB layout constraints. Check for any regional distribution restrictions or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when an octal high-side driver with robust fault protection is required. It is suitable for applications needing individual channel control via SPI or parallel interfaces. Consider the 120mΩ on-resistance and 1.67A current capability for load matching. Ensure the operating voltage range aligns with your system's power supply and load requirements. Verify thermal management needs given the 125°C junction temperature limit.

Part Context

The MAX14916 belongs to Maxim Integrated's industrial power switch family, designed for reliable performance in demanding environments. This series emphasizes durability and diagnostic capabilities, making it suitable for critical infrastructure and automotive applications.
