Overview
The INA201AIDGKT is a high-side current-shunt monitor produced by Texas Instruments. This device is part of the INA20x series, which includes the INA200, INA201, and INA202. The INA201AIDGKT is specifically designed to sense drops across shunts at common-mode voltages ranging from –16 V to 80 V. It features a voltage output and an integrated open-drain comparator with a 0.6-V internal voltage reference. The device operates from a single 2.7-V to 18-V supply and is available in both SOIC-8 and VSSOP-8 packages, making it suitable for a variety of applications requiring high-side current monitoring.
