Key Features
- 7-channel NPN Darlington array with 500 mA per channel and 50 V output voltage for driving relays and motors
- Built-in transient suppression diodes on each output protecting against inductive kickback up to 50 V
- Open-collector outputs compatible with 3.3 V and 5 V logic inputs enabling direct microcontroller interfacing
Applications
ULQ2003D1013TR is commonly used to drive relay coils, stepper motor windings, solenoids, and LED arrays from low-current microcontroller or FPGA GPIO outputs. With 7 independent channels in a single 16-pin package, it simplifies multi-output driver circuits in industrial automation panels, PLC output modules, and printer carriage actuators. The integrated flyback diodes eliminate the need for discrete protection components, reducing BOM count and PCB area significantly.

Frequently Asked Questions
Can ULQ2003D1013TR drive a 12 V relay coil directly from a 3.3 V microcontroller GPIO?
Yes, ULQ2003D1013TR accepts standard TTL and CMOS logic inputs down to 3.3 V on its base inputs while the open-collector outputs switch loads at up to 50 V and 500 mA per channel. A 12 V relay coil drawing 100 mA to 200 mA is well within the 500 mA per channel rating, and the built-in transient diodes clamp coil kickback spikes, protecting the IC and the microcontroller from inductive voltage transients.
How many stepper motor phases can a single ULQ2003D1013TR control in a unipolar stepper driver circuit?
ULQ2003D1013TR provides 7 independent Darlington channels, enough to drive one complete 4-phase unipolar stepper motor with 3 channels spare, or one 4-phase and one 3-phase motor simultaneously. Each channel handles 500 mA continuous current at up to 50 V, which matches the specifications of most NEMA 17 and NEMA 23 unipolar stepper coils used in 3D printers and CNC machines.
What is the voltage and current overhead margin when using ULQ2003D1013TR to switch 24 V industrial solenoids?
With a 50 V collector-emitter breakdown rating, using ULQ2003D1013TR on a 24 V supply leaves a 26 V margin above the nominal load voltage, comfortably absorbing inductive spikes even without external clamping. At 500 mA per channel, typical industrial solenoids rated 24 V at 200 mA to 400 mA operate at 40% to 80% of the rated output current, ensuring reliable long-term operation within the thermal dissipation limits of the 16-pin SO package.
