Its input voltage range spans 2.7V to 40V, making it suitable for monitoring 12V and 24V automotive rails as well as industrial supply buses without external level shifting. ## 8-TSSOP package and surface-mount board integration Surface-mount assembly with Tape & Reel packaging supports automated pick-and-place for volume production; the Cut Tape option works for prototype runs without committing to a full reel.","metaTitle":"INA139QPWRQ1 Current Monitor, ±0.5%, 2.7-40V, 8-TSSOP","metaDescription":"Texas Instruments INA139QPWRQ1 high-side current monitor, ±0.5% accuracy, 2.7V to 40V input, -40°C to 125°C, AEC-Q100, 8-TSSOP.
