Youmile INA3221 Triple Channel Current Voltage Monitor I2C Low High Side Power

Product Overview

This Youmile module features the INA3221, a triple-channel current and bus voltage monitor with an I2C-compatible interface. It is designed for accurate power monitoring and control applications, replacing the INA219 with expanded functionality.

Key Features

• Monitors current on buses from 0 V to 26 V.
• Operates from a single 2.7-V to 5.5-V supply with a typical supply current of 350 µA.
• High accuracy with a maximum offset voltage of ±80 µV and a maximum gain error of 0.25%.
• Three-channel monitoring of both shunt voltage drops and bus supply voltages.
• I2C and SMBUS compatible interface with four programmable addresses.
• Programmable conversion times and averaging modes for precise signal readings.
• Offers critical and warning alerts for out-of-range conditions on each channel.
• Supports both low-side and high-side current sensing.
