MCU-219 INA219 I2C interfészek Zero-Drift kétirányú áram / teljesítmény figyelő érzékelő modul

MCU-219 INA219 I2C interfaces Zero-Drift bi-directional current / power monitoring sensor module
 
Zero MCU-219 module is an I2C interface with a drift, bi-directional current / power monitor integrated circuit (IC), TI further expand the energy-saving electronic products camp. INA219 industry with the highest accuracy and the most compact size, can not only monitor the voltage drop across the shunt resistor, the shunt supply voltage sensing, while also computing power. The device SOT23 package can provide a small number of current sensing servers, laptops, power, battery management and automotive and telecommunications equipment, low cost solution.
 
INA219 from -40C to 1% of the maximum achievable accuracy error in  the temperature range of 85C, the maximum offset 100 uV. The combined advantages of high precision product 12-bit resolution, to help customers reduce the pressure drop across the shunt resistor as much as possible, thereby minimizing power losses and power consumption and board space. The device can be sensed bus voltage range of 0 V to 26 V.
 
INA219 Other important features include:
 
Programmable calibration register can be directly read current in amperes, and the reading power in watts.
Sampling can be averaged up to 128, in order to achieve filtering in noisy environments.
I2C interface has a timeout settings, not only to prevent bus lock, but may also provide high-speed mode, to meet the communication requirements of up to 3.4 MHz.
Support all the features of the INA219 are software programmable.
A single power supply, the operating voltage is between 3.0 to 5.5V.
