Frequently Asked Questions
What is the ULN2003LVPWR and what does it do?
The ULN2003LVPWR is a 7-channel low-voltage NPN Darlington transistor array from Texas Instruments. It allows low-voltage MCUs (1.8V/3.3V logic) to drive high-current inductive loads such as relays, solenoids, and stepper motors. Each channel sinks up to 250mA and includes an integrated flyback suppression diode.
What supply voltage does the ULN2003LVPWR require?
The ULN2003LVPWR operates with a supply voltage range of 1.65V to 5V, making it compatible with modern 1.8V and 3.3V MCU logic levels. This is the key differentiator from the standard ULN2003A which requires 5V logic.
What package is the ULN2003LVPWR and how many pins does it have?
The ULN2003LVPWR comes in a TSSOP-16 (Thin Shrink Small Outline Package) with 16 pins. The PWR suffix denotes the TSSOP package variant, which offers a smaller footprint compared to the SOIC package.
What are good alternatives to the ULN2003LVPWR?
Compatible alternatives include the ULN2003LVDR (SOIC-16 package, same electrical specs), ULN2003A (standard 5V version), and ULQ2003A for higher voltage. For pin-compatible low-voltage options, consider the TD62003AFG from Toshiba.
Is the ULN2003LVPWR RoHS compliant and what is its lifecycle status?
Yes, the ULN2003LVPWR is RoHS compliant and lead-free. It is in active production status at Texas Instruments as of 2026, with no end-of-life or NRND notices issued.
