MCU-3221 INA3221 Current Monitoring Module
Product Information:
The INA3221 is a three channel, high side current and bus voltage monitor with an I2C and SMBUS compatible interface. The INA3221 not only monitors shunt voltage drop and bus power supply voltage, but also provides programmable conversion time and average value calculation modes for these signals. The INA3221 provides critical and warning alarms for detecting multiple programmable out of range conditions on each channel.
The INA3221 senses the current on the bus (voltage varies from 0V to+26V). This device is powered by a single power supply of 2.7V to 5.5V, with a power supply current consumption of 350 μ A (typical value). The INA3221 has a rated operating temperature range of - 40 ° C to+125 ° C. An I2C and SMBUS compatible interface has four programmable addresses.
Product Characteristics:
● Three channel monitoring with respective bus voltages available.
● 0.1 ohm 1% 2W current detection resistance.
● Maximum detection voltage of 26V, accuracy of ± 8mV.
● Maximum ± 1.638A current measurement with ± 0.4mA accuracy.
● PCB size: 38 * 32 mm.
● Weight (excluding needle arrangement and others): 4.4g.
● Modules can be selected through pad jumpers using four I2C addresses: 0x40, 0x41, 0x44, 0x45.
