Specification: _x005f_x000D_ Origin: Mainland China _x005f_x000D_ Type: Module _x005f_x000D_ Condition: New _x005f_x000D_ Product Description: _x005f_x000D_ 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. _x005f_x000D_ 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. _x005f_x000D_ The I2C and SMBUS-compatible interface has four programmable addresses. _x005f_x000D_ Product Features: _x005f_x000D_ 1. Three channels with different bus voltages. _x005f_x000D_ 2. 0.1 ohm 1% 2W current sense resistor. 3. _x005f_x000D_ 3. Up to +26V target voltage with ±8mV resolution. 4. _x005f_x000D_ 4. Current measurement up to ±1.638A with resolution of ±0.4mA. _x005f_x000D_ 5. Size: 38*32*3mm. _x005f_x000D_ 6. The board/chip uses I2C 7-bit address 0x40, 0x41, 0x44, 0x45, selectable by jumper. _x005f_x000D_ Product Size: 38.00x32.00x3.00mm/1.5x1.26x0.12inch _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ 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! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1*Power Supply Voltage Sensor Board 1.
