Overview
The ULQ2003ATPWRQ1 is an automotive-grade Darlington transistor array manufactured by Texas Instruments. It integrates seven NPN Darlington pairs within a single integrated circuit, designed for high-voltage switching applications. The device operates with a collector-emitter voltage of up to 50 V and supports a maximum continuous DC collector current of 500 mA per channel. It is housed in a TSSOP-16 surface-mount package and is qualified under the AEC-Q100 standard for automotive reliability. The component functions effectively across an extended temperature range from -40°C to +125°C, making it suitable for harsh automotive environments.
Feature Summary
- Integrates seven independent NPN Darlington transistor pairs for multi-channel load driving
- Includes built-in internal clamping diodes on each output to suppress inductive voltage spikes
- Features high input impedance compatible with standard TTL or CMOS logic families
- AEC-Q100 qualified for robust performance in demanding automotive electronic systems
Applications
- Automotive solenoid and relay driver circuits
- High-side or low-side switching for automotive lighting loads
- Actuator control interfaces in vehicle body electronics
- General-purpose high-voltage switching in automotive modules
Procurement Notes
Verify the specific suffix TPWRQ1 against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the procurement source provides valid traceability records and confirms compliance with the AEC-Q100 qualification standards required for automotive integration.
Selection Notes
Select this component when designing circuits requiring multiple high-current switches driven directly by low-power logic signals. It serves as a direct replacement for the ULN2003 series in automotive contexts where higher thermal stability and extended operating temperatures are mandatory. Confirm that the application voltage does not exceed the 50 V rating and that heat dissipation requirements fit the TSSOP-16 thermal profile.
Part Context
This part belongs to the ULQ2003A family of automotive-rated Darlington arrays. It shares functional similarities with the commercial ULN2003 but offers enhanced durability and wider temperature tolerance specifically engineered for automotive electronics. The Q1 suffix indicates its qualification status, distinguishing it from non-automotive variants within the broader product line.
Replacement Considerations
The ULQ2003ADG4Q1 is a documented alternative variant within the same family. Verify pinout compatibility and ensure the replacement meets the same AEC-Q100 grade and thermal specifications before substitution.
