MAX14919AATP+T

Overview

The MAX14919AATP+T is a quad industrial low-side switch manufactured by Analog Devices Inc. It features four N-channel outputs with a maximum current of 800mA per channel and a typical on-resistance of 140mΩ. The device operates within a load voltage range of 4.5V to 5.5V and includes integrated fault protection against over-temperature, reverse current, short circuits, and under-voltage lockout. Additional features include a 5V regulator output and status flags. It is housed in a 20-TQFN (4x5) package.

Feature Summary

Integrates four independent low-side switches for precise load control
Provides comprehensive fault protection including thermal shutdown and reverse current blocking
Includes an integrated 5V linear regulator for auxiliary power supply needs
Offers real-time status monitoring through dedicated flag outputs

Applications

Industrial relay and solenoid driver circuits
Automotive lighting and actuator control systems
General-purpose power distribution in industrial equipment
Load switching in embedded control modules

Procurement Notes

Verify the specific suffix 'AATP' corresponds to the required tape-and-reel packaging configuration when ordering. Confirm that the 20-TQFN footprint matches your PCB layout constraints. Ensure the operating temperature range meets your application's environmental requirements. Cross-reference the datasheet for any recent design revisions or compliance updates before finalizing procurement.

Selection Notes

Select this component for applications requiring multiple low-side switches with high current capability and robust protection features. The integrated 5V regulator simplifies power management by providing a stable supply for internal logic or external sensors. Consider the 140mΩ on-resistance for efficiency calculations and thermal dissipation planning in dense circuit designs.

Part Context

This part belongs to the MAX14919 family of industrial power switches. It complements other Maxim Integrated solutions like the MAX14917 and MAX14916, which offer different channel counts and high-side configurations. The MAX14919 series is designed for demanding industrial environments where reliability and fault protection are critical for system uptime.
