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

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 shunt 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.
