It measures current by sensing the voltage drop across an external shunt resistor on the supply rail, with ±0.5% accuracy over the full operating range. Packaged in an 8-TSSOP, the INA168QPWRQ1 is a surface-mount part suited for compact ECU and module layouts where board space is constrained. ## High-side sensing — no ground-path disturbance High-side sensing means the monitor sits between the supply and the load, measuring current without injecting errors into the ground path. This is preferred in automotive and industrial designs where ground shifts or shared ground returns would corrupt a low-side measurement. ## Active lifecycle — no LTB risk for current production The INA168QPWRQ1 carries an active lifecycle status with ROHS3 compliance. There is no last-time-buy or end-of-life notice in effect, making it suitable for new designs and ongoing production without obsolescence watch.","metaTitle":"INA168QPWRQ1 Automotive Current Monitor, AEC-Q100, ±0.5%","metaDescription":"TI INA168QPWRQ1 high-side current monitor, AEC-Q100 qualified, ±0.5% accuracy, 2.7V-60V input, -40°C to 125°C, 8-TSSOP.","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)","Accuracy":"±0.5%","Function":"Current Monitor","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP (0.173\\\", 4.40mm Width)","Sensing Method":"High-Side","Voltage - Input":"2.7V ~ 60V","lifecycle_stage":"eol_hot","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"8-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.24","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.24000","currency":"USD"},{"qty":10,"price":"$2.91100","currency":"USD"},{"qty":25,"price":"$2.75240","currency":"USD"},{"qty":100,"price":"$2.38530","currency":"USD"},{"qty":250,"price":"$2.26300","currency":"USD"},{"qty":500,"price":"$2.03058","currency":"USD"},{"qty":1000,"price":"$1.73100","currency":"USD"},{"qty":2000,"price":"$1.73100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e6e5f4c81d00d8481674f736ed7380a7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is INA168QPWRQ1 AEC-Q100 qualified?","answer":"Yes, the INA168QPWRQ1 is part of the Automotive, AEC-Q100 series and is fully qualified to AEC-Q100.
