Overview
The ULQ2003ATDRQ1 is an automotive-grade high-voltage, high-current Darlington transistor array manufactured by Texas Instruments. It integrates seven open-collector Darlington pairs with common emitters within a single 16-pin SOIC package. Each channel supports a maximum collector current of 500 mA and withstands peak currents up to 600 mA, while the output voltage rating reaches 50 V. The device operates across an extended temperature range from -40°C to +105°C. Integrated suppression diodes are included for inductive load driving, and inputs are pinned opposite outputs to simplify board layout.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards
- Integrated suppression diodes for inductive load protection
- TTL, CMOS, PMOS, and DTL compatible input logic levels
Applications
- Driving solenoids and relays
- Controlling DC motors
- Power buffering for LED displays
- Thermal print-head actuation
Procurement Notes
Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific order code matches the ULQ2003ATDRQ1 designation to ensure correct automotive grade and SOIC-16 packaging specifications. Review the latest datasheet for any potential design changes or end-of-life notices prior to final procurement decisions.
Selection Notes
Select this component when designing circuits requiring multiple high-current switching channels with integrated flyback protection. Ensure the application logic levels align with the specified TTL/CMOS compatibility. Verify that the thermal management strategy accommodates the power dissipation characteristics inherent to Darlington arrays under continuous load conditions.
Part Context
This part belongs to the ULQ2003A series of Darlington arrays, specifically tailored for automotive applications. It shares functional similarities with commercial variants like the ULQ2003AD but meets stricter automotive reliability requirements. The 'TDRQ1' suffix indicates tape-and-reel packaging and automotive qualification status.
Replacement Considerations
Direct substitutes include other automotive-qualified Darlington arrays such as the ULN2003AQDRQ1 if pinout compatibility is maintained. Verify equivalent current ratings and suppression diode configurations before substitution.
