Specification: Origin: Mainland China Type: Module Condition: New Product Description: The NA3221 is a three-channel high-side current and bus voltage monitor with I2C and SMBUS-compatible interfaces.The INA3221 monitors shunt voltage drops and bus supply voltages in addition to programmable transition times and averaging modes for these signals.The INA3221 provides both critical alarms and warning alarms for detecting multiple programmable out-of-range conditions for each channel. The INA3221 senses current on the bus from 0V to 26V. The device is powered from a single 2.7V to 5.5V supply and consumes 350uA (typical) of supply current.The INA3221 is rated for operation over the -40°C to +125°C temperature range. The I2C and SMBUS-compatible interface has four programmable addresses. Product Features: 1. Three channels with different bus voltages. 2. 0.1 ohm 1% 2W current sense resistor. 3. 3. Up to +26V target voltage with ±8mV resolution. 4. 4. Current measurement up to ±1.638A with resolution of ±0.4mA. 5. Size: 38*32*3mm. 6. The board/chip uses I2C 7-bit address 0x40, 0x41, 0x44, 0x45, selectable by jumper. Product Size: 38.00x32.00x3.00mm/1.5x1.26x0.12inch Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1*Power Supply Voltage Sensor Board 1.
