MAX14917AFM+

Overview

The MAX14917AFM+ is an industrial octal high-side driver featuring integrated diagnostics. It supports a supply voltage range of 2.5V to 5.5V and drives loads between 10V and 36V. The device provides eight independent outputs with a typical on-resistance of 120 milliohms and a maximum output current of 1.67A per channel. It utilizes SPI or parallel interfaces for control. Operating temperatures range from -40°C to +125°C. The component is housed in a 48-FCQFN (6x6) package.

Feature Summary

• Octal high-side switching architecture with individual channel control
• Integrated diagnostic features including overcurrent, overtemperature, and open-load detection
• Flexible interface options supporting both Serial Peripheral Interface and parallel logic inputs

Applications

• Industrial automation systems requiring multi-channel power distribution
• Smart power control units in manufacturing equipment
• Load drivers for sensor arrays and actuators in harsh environments

Procurement Notes

Verify the specific suffix and manufacturer details against official Analog Devices documentation to ensure authenticity. Confirm that the 48-FCQFN package matches your board layout requirements. Check for any lead-free compliance certifications if required by your assembly standards. Ensure the operating temperature range aligns with your environmental specifications.

Selection Notes

Select this component when multiple high-side switches are needed in a compact form factor. The integrated diagnostics simplify fault handling compared to discrete solutions. Consider the 120 milliohm on-resistance for efficiency calculations. Verify that the 36V load voltage capability meets your system's maximum requirements. Evaluate the SPI interface speed against your control loop timing constraints.

Part Context

This part belongs to the MAX14917 family of smart power controllers designed for industrial applications. It consolidates eight high-side switches with protection circuits into a single IC. The design targets applications requiring reliable power management and real-time status monitoring. It replaces multiple discrete MOSFETs and driver circuits, reducing board space and complexity.

Replacement Considerations

The MAX14916AFM+T is a documented substitute within the same product family. Both devices share the octal high-side configuration and similar diagnostic capabilities. Verify pin compatibility and interface settings before substitution. Ensure the replacement meets the same thermal and electrical specifications.
