Overview
The ULQ2003AD is a high-voltage, high-current Darlington transistor array manufactured by Texas Instruments. It integrates seven NPN Darlington pairs within a single package, providing a total of seven independent channels. Each channel supports a maximum continuous collector current of 500 mA and can withstand peak currents up to 600 mA. The device features a maximum collector-emitter voltage (Vceo) of 50 V and an integrated common cathode clamp diode for inductive load suppression. It operates within a temperature range of -40°C to +85°C and is housed in a 16-pin SOIC-Narrow surface-mount package.
Feature Summary
- Integrates seven open-collector Darlington pairs with common emitters for versatile switching applications
- Includes built-in suppression diodes to manage reverse voltage from inductive loads
- Features input pins positioned opposite output pins to facilitate simplified printed circuit board layout
Applications
- Driving solenoids and relays
- Controlling DC motors
- Powering LED displays and filament lamps
- Actuating thermal print-heads
- Serving as high-power buffers
Procurement Notes
Verify the specific manufacturer part number against official documentation to ensure compatibility with design requirements. Confirm that the component meets necessary environmental standards such as RoHS compliance before integration into final products. Cross-reference datasheet specifications for electrical limits to prevent operational failures.
Selection Notes
Select this component when driving moderate to high-current loads requiring high voltage tolerance. The integrated clamp diodes make it suitable for inductive loads without external protection components. Ensure the application logic levels are compatible with TTL, CMOS, PMOS, or DTL inputs. Consider the SOIC-16 package constraints for thermal management and physical space availability on the circuit board.
Part Context
This device belongs to the ULQ2003A series of Darlington arrays. It shares functional similarities with other members like the ULN2003AN but utilizes a surface-mount SOIC-16 package instead of through-hole PDIP. The ULQ variant typically denotes automotive-grade qualification options in certain packaging configurations, offering extended temperature ranges compared to standard commercial versions.
Replacement Considerations
The ULQ2003ADR serves as a tape-and-reel alternative to the tube-packaged ULQ2003AD. Both share identical electrical characteristics and pinouts. Verify package dimensions and lead finish specifications to ensure mechanical compatibility during substitution.
