It measures current by sensing the voltage drop across a shunt resistor and outputs a rail-to-rail voltage proportional to that drop. ## Package and rework — SOT-23-5 The INA180B4QDBVRQ1 comes in a SOT-23-5 package. Five pins, standard footprint. The 197 µA quiescent current means minimal self-heating. ## Temperature grade and environment Rated for -40°C to 125°C ambient, this part covers under-hood automotive, industrial motor drives, and outdoor telecom enclosures. The AEC-Q100 qualification means it has passed the stress tests for automotive-grade reliability — extended temperature cycling, HAST, and latch-up. For a BOM line that needs a current-sense amp in a 105°C cabinet or an engine-bay ECU, this is the tier to specify. ## Sourcing and lifecycle The INA180B4QDBVRQ1 is listed as Active and ROHS3 compliant. The base product number is INA180, so the gain version and Q1 automotive grade are fixed in this suffix — no field-configurable options.","metaTitle":"INA180B4QDBVRQ1 Automotive Current Sense Amplifier, 105 kHz","metaDescription":"TI INA180B4QDBVRQ1 AEC-Q100 current sense amplifier in SOT-23-5. 105 kHz bandwidth, 197 µA supply, -40°C to 125°C.
