MAX14900EAGM+T

Overview

The MAX14900EAGM+T is an octal high-side intelligent power switch featuring eight independent channels. It operates with a supply voltage range of 4.5V to 5.5V and supports load voltages from 10V to 36V. Each channel delivers up to 850mA continuous current with a typical on-resistance of 85mΩ. The device integrates comprehensive protection mechanisms including fixed current limiting, overtemperature shutdown, overvoltage protection, under-voltage lockout (UVLO), and open-load detection. Communication is facilitated via SPI or parallel interfaces, and it includes status flags for monitoring.

Feature Summary

• Integrates eight high-side switches with individual control and status feedback
• Provides robust fault protection including current limiting, thermal shutdown, and open-load detection
• Supports digital control through SPI or parallel interface configurations

Applications

• Industrial motor control systems requiring multi-channel power distribution
• Automotive electronic control units (ECUs) for actuator driving
• General-purpose load switching in embedded systems

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure compatibility with 36V load environments and check for RoHS compliance documentation. Validate that the 48-QFN package matches your PCB footprint requirements before procurement.

Selection Notes

Select this component for applications requiring multiple high-side outputs with integrated diagnostics. It is suitable where space efficiency is critical due to the QFN package. Consider the 850mA per-channel limit and the need for SPI/parallel control logic. Evaluate thermal management needs given the 125°C junction temperature rating.

Part Context

This part belongs to the MAX14900 family of intelligent power switches designed by Maxim Integrated, now part of Analog Devices. These devices are engineered for reliable power distribution in harsh environments. The EAGM+ variant specifies the lead-free, halogen-free construction and the specific 48-QFN package type used in compact designs.
