The Texas Instruments INA3221AIRGVT is a versatile three-channel, high-side current and bus voltage monitor. It features an I2C and SMBUS-compatible interface, enabling precise monitoring of shunt voltage drops and bus supply voltages.
This device offers high accuracy with a maximum input offset voltage of ±80µV and a gain error of 0.25%. It supports a common-mode voltage range from 0V to 26V and operates from a single 2.7V to 5.5V supply. Programmable conversion times and averaging modes allow for signal customization, while alert and warning outputs provide critical out-of-range notifications.
The INA3221AIRGVT is available in a 16-VQFN (4x4 mm) package, suitable for surface mounting. Its design facilitates sensing current on buses that can vary widely, making it ideal for power management applications requiring detailed current and voltage oversight.
