Overview
The ULQ2004ATDRG4Q1 is an automotive-grade high-voltage, high-current Darlington transistor array manufactured by Texas Instruments. It integrates seven NPN Darlington pairs with common emitters and includes built-in clamp diodes across each output to the emitter for inductive load protection. The device features a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 500 mA per channel. It operates within an extended temperature range from -40°C to +125°C and complies with AEC-Q100 qualification standards. The component is housed in a surface-mount SOIC-16 package.
Feature Summary
- Automotive-grade reliability compliant with AEC-Q100 standards
- Integrated flyback clamp diodes for inductive load protection
- High-voltage capability suitable for driving relays and solenoids
Applications
- Automotive relay driver circuits
- Solenoid control modules
- Industrial motor interface applications
Procurement Notes
Verify that the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status through official manufacturer documentation. Ensure the ordering part number matches the required SOIC-16 package variant. Confirm RoHS compliance details directly from the datasheet before procurement.
Selection Notes
Select this component when designing for automotive environments requiring robust inductive load switching. The integrated clamping diodes simplify circuit design by eliminating external components. Verify that the 500 mA per-channel current rating meets the specific load requirements of the target application.
Part Context
This part belongs to the ULQ2004A series of Darlington arrays designed specifically for automotive electronics. It shares functional similarities with the ULN2004A but includes enhanced qualification for harsh operating conditions. The Q1 suffix denotes automotive grade certification, distinguishing it from standard commercial variants.
Replacement Considerations
The ULN2003A is a similar Darlington array but typically lacks the specific automotive qualification and may have different pin configurations or current ratings. Verify compatibility carefully as direct pin-for-pin substitution requires confirmation of electrical specifications and package dimensions.
