ULQ2003ATDRG4Q1

Overview

The ULQ2003ATDRG4Q1 is an automotive-grade NPN Darlington transistor array manufactured by Texas Instruments. It integrates seven open-collector Darlington pairs within a single 16-pin SOIC package. Each channel supports a maximum collector current of 500 mA with peak currents reaching 600 mA, while the output voltage rating is 50 V. The device operates across an extended temperature range from -40 °C to +105 °C and complies with AEC-Q100 standards for automotive applications.

Feature Summary

Integrates seven high-voltage Darlington pairs in a compact surface-mount package
Includes built-in suppression diodes suitable for driving inductive loads
Features input-output pinning arrangement to simplify printed circuit board layout

Applications

Automotive relay driver circuits
Solenoid control systems
DC motor interface modules

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q100 qualification requirements for the intended automotive environment before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring multiple high-current switching channels in a limited footprint. Verify that the 500 mA per-channel limit accommodates the load requirements and that the integrated flyback diodes align with the system's inductive load management strategy.

Part Context

This part belongs to the ULQ2003A family of high-voltage Darlington arrays designed for robust switching applications. The 'Q1' designation indicates compliance with automotive reliability standards, distinguishing it from commercial variants while maintaining functional compatibility with standard logic families.
