Overview
The ULQ2004ADG4 is a high-voltage, high-current Darlington transistor array manufactured by Texas Instruments. It integrates seven independent NPN Darlington pairs within a single SOIC-16 surface-mount package. Each channel provides a continuous collector current of 500 mA and can withstand peak currents up to 600 mA. The device supports an output voltage of 50 V with a maximum power dissipation of 950 mW. It operates over an extended temperature range from -40°C to +105°C. Internal suppression diodes are included for inductive load driving, and inputs are pinned opposite outputs to simplify board layout.
Feature Summary
- Integrates seven open-collector Darlington pairs with common emitters for versatile switching applications.
- Includes integrated suppression diodes to protect against inductive load back-EMF.
- Features input-output pin opposition to facilitate simplified printed circuit board layout.
Applications
- Driving solenoids and relays
- Controlling DC motors
- Powering LED displays and filament lamps
Procurement Notes
Verify the specific suffix G4 indicates lead-free compliance and RoHS status before procurement. Confirm the manufacturer source as Texas Instruments rather than the distributor hosting the document. Ensure the SOIC-16 package dimensions match the target PCB footprint requirements.
Selection Notes
Select this component when seven independent high-current switches are required in a compact surface-mount form factor. Compare thermal resistance characteristics against DIP alternatives if heat dissipation is critical. Verify logic family compatibility for TTL, CMOS, PMOS, or DTL inputs to ensure proper interface design.
Part Context
This part belongs to the ULQ2004 series of high-voltage Darlington arrays. It serves as a surface-mount alternative to through-hole packages like the ULQ2004AN. The device is designed for general-purpose high-current switching tasks where multiple isolated channels are needed.
Replacement Considerations
Direct substitutes include other ULQ2004 variants such as ULQ2004AD or ULQ2004DR. Cross-manufacturer equivalents may exist but require verification of pinout and electrical specifications.
