INA3221 3-Channel Current and Voltage Monitor Module, I2C/SMBus, 0-26V, ±1.638A

INA3221 is a three-channel, high-side current and total line voltage monitor with an interface compatible with 2C and SMBUS. INA3221 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. Ino3221 provides key alarms and warning alarms to detect various out-of-range conditions programmable on each channel. Ino3221 sense the current on the bus (the voltage varies from 0V to +26V). This device is powered by A single power supply from 2.7V to 5.5V, and the ICC, IDD consumption is 350 μA (typical value). The rated operating temperature range of INA3221 is-40°C to +125°C. Interfaces compatible with 2C and SMBUS have four programmable addresses. Features: three-channel monitoring, each bus voltage can be used 0.1 ohms 1% 2W current detection electronic resistance. Maximum 26v detection voltage, ± 8mV accuracy. The highest ± 1.638A current measurement, ± 0.4 Ma accuracy. PCB size: 38*32mm. Weight (excluding pin arrangement and others): 4.4g. The module can be selected through the pad wire jumper, using 4 2c addresses: 0 x40, 0 x41, 0 x44, 0 x45. Triple-Channel with different bus voltage. 0.1 ohm 1% 2W current sense resistor. Up to +26V target voltage, with ±8mV resolution. Up to ±1.638A current measurement, with ±0.4mA resolution. Dimension: 38*32mm. PCB (no header or terminal block): 4.4g. This board/chip uses I2C 7-bit addresses 0x40, 0x41, 0x44, 0x45, selectable with jumpers
