MCU-3221 INA3221 three-way low-side / high-side output current I2C / Power Monitor
INA3221 it is a three-channel, high-side current and bus voltage monitor with one compatibility I2 C and SMBUS the interface.
INA3221 it can not only monitor the shunt voltage drop and bus power supply voltage, but also provide programmable conversion time and average value calculation mode for these signals.
INA3221 provides Key alarms and warning alarms to detect multiple out-of-range conditions programmable on each channel.
INA3221 sensing bus (voltage in 0V to + 26V change within the scope).
This device is made up 2.7V to 5.5V single power supply, ICC, IDD consumption is 350μA(Typical value).
INA3221 the rated operating temperature range is -40°C to +125°C. Compatible I2C and SMBUS the interface of has four programmable addresses.
