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.","metaTitle":"ULQ2003ATPWRQ1 Automotive Relay/Solenoid Driver","metaDescription":"ULQ2003ATPWRQ1 – AEC-Q100 qualified 7-channel low-side NPN driver for relays and solenoids. 50V max load, 500mA per channel, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"Parallel","Input Type":"Inverting","Output Type":"NPN","Switch Type":"Relay, Solenoid Driver","Mounting Type":"Surface Mount","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width)","Voltage - Load":"50V (Max)","lifecycle_stage":"eol_hot","Number of Outputs":"7","Output Configuration":"Low Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 105°C (TA)","Current - Output (Max)":"500mA","Supplier Device Package":"16-TSSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.83","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.83000","currency":"USD"},{"qty":10,"price":"$0.73100","currency":"USD"},{"qty":100,"price":"$0.56050","currency":"USD"},{"qty":500,"price":"$0.44308","currency":"USD"},{"qty":1000,"price":"$0.35446","currency":"USD"},{"qty":2500,"price":"$0.32123","currency":"USD"},{"qty":5000,"price":"$0.31350","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1984e06f756b941cb117d7c4733de5b3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ULQ2003ATPWRQ1 AEC-Q100 qualified?","answer":"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."},{"question":"What is the closest pin-compatible alternative to ULQ2003ATPWRQ1?","answer":"The ULQ2003ATPWRQ1 is the automotive-qualified variant of the standard ULQ2003A family.
