Product details

What this driver is and where it fits

The Texas Instruments ULQ2003ATPWRQ1 is a seven-channel low-side NPN Darlington driver array qualified to AEC-Q100 for automotive applications. It switches inductive loads like relays, solenoids, and small DC motors up to 50 V and 500 mA per channel, with an inverting input and a 1:1 input-to-output ratio. The parallel interface and lack of a Vcc supply pin (base drive is self-biased) simplify the BOM for multiplexed lamp or actuator banks in body controllers, transmission solenoids, and HVAC flap drives.

Temperature range and environment

Rated for -40°C to 105°C ambient, this driver covers the full automotive cabin and under-hood temperature envelope. The AEC-Q100 qualification means it has passed the stress tests that production automotive modules require.

Lifecycle and sourcing

The ULQ2003ATPWRQ1 carries an active lifecycle status with ROHS3 compliance. It is a current-production part, not a last-time-buy or obsolete line — no immediate replacement risk for new designs or ongoing production.

Frequently asked questions

Is ULQ2003ATPWRQ1 AEC-Q100 qualified?

Yes, the ULQ2003ATPWRQ1 is part of the Automotive, AEC-Q100 series, meaning it has passed the automotive-grade stress and reliability tests required for deployment in vehicle electronics.

What is the closest pin-compatible alternative to ULQ2003ATPWRQ1?

The ULQ2003ATPWRQ1 is the automotive-qualified variant of the standard ULQ2003A family. The commercial-grade ULQ2003A (in the same 16-TSSOP package) is pin-compatible but lacks AEC-Q100 qualification. For a direct automotive-grade drop-in, stick with this exact order code.
