MAX14916AAFM+T

Overview

The MAX14916AAFM+T is an industrial-grade octal high-side driver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates eight independent high-side switches within a compact 48-lead FCQFN package measuring 6x6 mm. The device supports load voltages ranging from 10V to 36V and operates with supply voltages between 2.5V and 5.5V. Each channel delivers a maximum output current of 1.67A with a typical on-resistance of 120 milliohms. Control interfaces include SPI and parallel modes, while integrated protections cover overtemperature, undervoltage lockout, fixed current limiting, and open-load detection.

Feature Summary

• Integrates eight independent high-side power switches in a single compact package
• Provides comprehensive fault protection including overtemperature, UVLO, and open-load detection
• Supports flexible control via both Serial Peripheral Interface (SPI) and parallel logic inputs

Applications

• Industrial automation systems requiring multi-channel power distribution
• Automotive electronic control units and lighting management
• Consumer electronics appliances with complex load switching requirements

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required temperature range and packaging configuration. Request original datasheets and compliance certificates to ensure adherence to quality standards before finalizing acquisition.

Selection Notes

Evaluate thermal performance under maximum load conditions due to the dense integration of eight channels. Ensure the system voltage remains within the specified 10V to 36V range for reliable operation. Consider the 120 milliohm on-resistance impact on overall power efficiency and heat dissipation requirements in the final design.

Part Context

This component belongs to the MAX14916 family of industrial octal high-side drivers designed for robust power management applications. It serves as a critical interface between low-voltage digital controllers and higher-voltage loads, offering precise switching capabilities and extensive diagnostic features for enhanced system reliability.

Replacement Considerations

Consult official documentation for cross-reference data regarding compatible substitutes. Verify pin compatibility and electrical specifications before considering alternative components from other manufacturers.
