MAX14916AFM+T

Overview

The MAX14916AFM+T is an industrial octal high-side switch IC designed for power distribution applications. It features eight independent high-side switches, each capable of delivering up to 1.1A minimum continuous current with a typical on-resistance of 120 milliohms. The device operates within a load voltage range of 10V to 36V and supports a supply voltage of 2.5V to 5.5V. Key protection features include fixed overcurrent limit, open-load detection, overtemperature shutdown, and undervoltage lockout (UVLO). It utilizes SPI and parallel interfaces for control and status reporting via state flags.

Feature Summary

• Octal configuration providing eight independent high-side switches for versatile power distribution
• Integrated fault protection including overcurrent limiting, open-load detection, and thermal shutdown
• Low on-resistance design to minimize power loss and heat generation during operation
• Flexible interface options supporting both Serial Peripheral Interface (SPI) and parallel control modes

Applications

• Industrial power distribution systems requiring multiple isolated loads
• Automotive electronic control units (ECUs) and body electronics
• General-purpose load switching in harsh environment equipment
• Power management modules in industrial automation controllers

Procurement Notes

Verify the specific suffix 'AFM' to ensure the correct package variant (48-FCQFN) and temperature grade are selected. Confirm RoHS compliance status through official documentation as '+T' indicates lead-free packaging. Check current availability status directly with authorized distributors, as supply constraints may affect immediate procurement. Ensure the ordering part number matches the exact pinout and electrical specifications required by the target application design.

Selection Notes

Select this component when multiple high-side switching channels are required in a compact footprint. The 120 milliohm on-resistance makes it suitable for moderate current loads up to 1.1A per channel. Consider the integrated diagnostic features like open-load detection if system monitoring is critical. Verify that the 10V to 36V load voltage range aligns with the system's power rails. The choice between SPI and parallel interface should depend on available microcontroller resources and speed requirements.

Part Context

This device belongs to the MAX14916 series of high-side drivers from Analog Devices/Maxim Integrated. It is part of a family of power distribution ICs designed for robust industrial and automotive applications.
