High-side current monitor with ±0.5% accuracy across 2.7V to 40V
The Texas Instruments INA139QPWRQ1 is a high-side current monitor that measures load current by sensing the voltage drop across an external shunt resistor, delivering a proportional output current with ±0.5% accuracy. 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.
