MAX14900EAGM+CKT

Overview

The MAX14900EAGM+CKT is an octal high-speed high-side switch from Analog Devices. It features eight independent channels with a 1:1 input-to-output ratio, supporting load voltages from 10V to 36V and a supply voltage of 4.5V to 5.5V. Each channel delivers a maximum output current of 850mA with a typical on-resistance of 85mΩ. The device integrates comprehensive fault protection including fixed current limiting, open-load detection, over-temperature shutdown, over-voltage protection, and under-voltage lockout (UVLO). It utilizes SPI and parallel interfaces for control and status reporting within a 48-QFN package.

Feature Summary

Octal configuration providing eight independent high-side power switching channels
Integrated diagnostic capabilities including open-load detection and status flags
Comprehensive fault protection mechanisms covering thermal, electrical, and load anomalies

Applications

Industrial power distribution systems
Automotive electronic control units
Load switching in complex embedded architectures

Procurement Notes

Verify the specific suffix CKT against official manufacturer documentation to confirm tape-and-reel packaging requirements. Ensure compatibility with existing PCB footprints and SPI interface configurations. Cross-reference the exact part number with authorized distributors to confirm availability and authenticity, as component variants may differ in packaging or minor specifications.

Selection Notes

Select this component when multiple isolated high-side switches are required within a single footprint. Evaluate the 85mΩ on-resistance against thermal dissipation constraints at full load. Confirm that the 36V maximum load voltage aligns with system bus requirements. Verify that the integrated fault protection features meet safety standards for the target application environment.

Part Context

This part belongs to the MAX14900 family of intelligent power switches designed for robust industrial and automotive applications. It consolidates multiple discrete switching components into a single integrated circuit, reducing board space and simplifying design complexity while maintaining high reliability through built-in diagnostics and protection.
