CJMCU-3221 INA3221 Triple-way Low Side / High Side I2C Output Current Power Monitor Module

The INA3221 is a three-channel high-side current and bus voltage monitor with an I2C- and SMBUS-compatible interface. The INA3221 monitors both direct voltage drops and bus supply voltages in addition to having programmable conversion times and averaging modes for these signals. The INA3221 offers both critical and warning alerts to detect multiple programmable out-of-range conditions for each channel.The INA3221 senses current on buses that can vary from 0 V to 26 V. The device is powered from a single 2.7-V to 5.5-V supply and draws 350 µA (typ) of supply current.
