It monitors current on the high or low side of the supply rail, converting the voltage across an external shunt resistor into a ground-referenced output. ## Package and assembly Housed in a 6-pin SC-70-6 (also known as SOT-363), the part is surface-mount. The supplier device package is SC-70-6.","metaTitle":"INA199B2QDCKRQ1 Current Sense Amplifier, AEC-Q100, SC-70-6","metaDescription":"INA199B2QDCKRQ1 automotive current-sense amplifier from TI, ±1.5% accuracy, -0.1V to 26V input, SC-70-6 package.
