Overview
The ULQ2003AQDRQ1 is an automotive-grade high-voltage, high-current Darlington transistor array manufactured by Texas Instruments. It integrates seven independent NPN Darlington pairs within a single SOIC-16 package. The device supports a collector-emitter voltage of 50 V and delivers a maximum DC collector current of 500 mA per channel. Designed for robust operation, it functions across an extended temperature range from -40°C to +105°C. The component meets AEC-Q100 qualification standards, ensuring reliability for demanding automotive electronic applications requiring high switching capabilities.
Feature Summary
- Integrates seven independent NPN Darlington transistor pairs for multi-channel switching
- Engineered with internal base resistors to simplify logic interface connections
- Qualified for automotive environments under AEC-Q100 standards
- Features high-voltage tolerance suitable for inductive load driving
Applications
- Automotive relay driver circuits
- Solenoid control modules
- High-current LED lighting arrays
- DC motor control interfaces
Procurement Notes
Verify the specific suffix 'QDRQ1' against the manufacturer's latest datasheet to confirm the tape-and-reel packaging configuration and automotive grade designation. Ensure the ordering part number matches the required SOIC-16 surface-mount variant. Cross-reference the revision level to guarantee compatibility with existing design specifications before finalizing procurement orders.
Selection Notes
Select this component when designing systems that require multiple high-current switching channels within a compact footprint. It serves as a direct replacement for standard ULN2003 series devices where automotive qualification and extended temperature performance are mandatory. Verify that the input logic levels align with the internal base resistor values to ensure proper saturation during operation.
Part Context
This device belongs to the ULQ200xA-Q1 family of high-voltage Darlington arrays specifically developed for automotive electronics. It shares functional similarities with the commercial ULN2003 series but incorporates enhanced reliability features and stricter manufacturing controls required for vehicle integration. The QDRQ1 suffix denotes the specific automotive-grade version packaged in a reel format for automated assembly processes.
Replacement Considerations
The ULQ2003ADG4 is a related Texas Instruments part number within the same product family. Designers should verify if the commercial grade of the non-Q1 variant meets the thermal and reliability requirements of the target application before substituting.
