MAX14919AUP+T

Overview

The MAX14919AUP+T is a quad industrial low-side power switch IC manufactured by Analog Devices/Maxim Integrated. It integrates four independent high-current switches designed for robust power distribution in demanding environments. The device features a typical on-resistance (Rds(on)) of 140mΩ per channel, ensuring efficient power delivery with minimal voltage drop. It operates within an extended temperature range of -40°C to +125°C (TA), suitable for industrial applications. The component supports a supply voltage range compatible with standard 3.3V and 5V systems, providing reliable control for peripheral loads.

Feature Summary

• Integrates four independent low-side switches for multi-channel load control
• Features low on-resistance for efficient power distribution and reduced heat generation
• Designed for industrial-grade reliability with extended temperature operation capabilities

Applications

• Industrial automation control systems
• Power distribution units in embedded systems
• Peripheral load switching in automotive electronics

Procurement Notes

Verify the exact ordering part number against the manufacturer's current datasheet to ensure compatibility with specific package and tape/reel requirements. Confirm that the lead time and availability status align with project schedules, as industrial components may experience supply fluctuations. Ensure compliance with RoHS directives if required by the target market regulations.

Selection Notes

Select this component when multiple low-side switching channels are required in a compact footprint. The 140mΩ Rds(on) makes it suitable for moderate current applications where efficiency is critical. Consider the SOIC-16 package constraints for PCB layout. Verify that the input logic levels match the controlling microcontroller or FPGA outputs for reliable switching performance.

Part Context

This part belongs to the MAX14919 series of industrial power switches. It is distinct from high-side variants like the MAX14917 or other channel counts in the family. The 'UP' suffix indicates the SOIC-16 package type, while '+T' denotes the tape and reel packaging format. It serves as a dedicated solution for distributing power to multiple peripherals in space-constrained industrial designs.

Replacement Considerations

Direct replacements should be sought within the MAX14919 series for pin-compatible upgrades. Cross-referencing with other quad low-side switches from Analog Devices is recommended if current ratings or package types differ. Verify functional equivalence regarding on-resistance and thermal characteristics before substitution.
