Overview
The ULQ2003ADG4 is a high-voltage, high-current Darlington transistor array manufactured by Texas Instruments. It integrates seven NPN Darlington pairs within a single SOIC-16 surface-mount package. The device features a maximum collector-emitter voltage of 50 V and supports a maximum DC collector current of 500 mA per channel. It operates reliably across an extended temperature range from -40°C to +85°C. The component includes built-in clamp diodes for inductive load switching and pull-down resistors on input pins to prevent floating states.
Feature Summary
- Integrates seven independent NPN Darlington pairs for multi-channel switching applications
- Includes internal clamp diodes connected to the common output pin for inductive load protection
- Features integrated pull-down resistors on control inputs to ensure stable logic levels
Applications
- Driving relays and solenoids
- Switching incandescent lamps
- Controlling stepper motors
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm lead-free compliance and RoHS status. Confirm the package type matches the required SOIC-16 footprint. Check for any product discontinuation notices or lifecycle changes directly from Texas Instruments before finalizing procurement plans.
Selection Notes
Select this component when a single IC solution is required to drive multiple inductive loads with high voltage tolerance. Ensure the design accommodates the thermal dissipation requirements associated with the SOIC-16 package. Verify that the 50V rating and 500mA current capacity meet the specific load specifications of the target application.
Part Context
This part belongs to the ULQ2003A series of high-voltage Darlington arrays. It serves as the equivalent variant of the through-hole ULN2003AN but utilizes a surface-mount SOIC-16 package. The 'G4' suffix typically indicates a lead-free and RoHS-compliant manufacturing version within the Texas Instruments portfolio.
Replacement Considerations
The ULQ2003ADR is a reel-packaged variant of the same functional device. Cross-reference with other ULQ2003A series members if different packaging options are required.
