Description in Chinese:

 

 
 
The CMCU-219 Module Is a Zero Drift, Bidirectional Current/Power Supply Monitoring Integrated Circuit (IC) with I2C Interface, Which Further Expands TI's Energy-Saving Electronic Product Camp.INA219With the Industry's Degree and Type Size, It Can Not Only Monitor the Voltage Drop on the Shunt Resistor, Sense the Shunt Supply Voltage, but Also Calculate the Power Supply. The Device UsesSOT23The Package Can Provide Small and Low-Cost Solutions for Digital Current Sensing of Servers, Laptops, Power Supplies, Battery Management, and Vehicle-Mounted and Telecommunications Equipment.
 
INA219-40Cto 85CThe Error Accuracy of 1% Can Be Achieved Within the Temperature Range of, and the Offset Is 100 UV. The High Precision of This Product Combined with the Advantages of 12-Bit Resolution Can Help Customers Reduce the Voltage Drop on Shunt Resistor as Much as Possible, Thus Reducing Power Loss and Power Consumption and Saving Board-Level Space. The Bus Voltage Range That the Device Can Sense Is 0 V to +26V.
 
Other Important Features of INA219 Include:
 
The Programmable Calibration Register Can Directly Read the Current in Ampere and the Power Supply in Watt.
up128One Average Sampling to Filter in Noisy Environment.
The I2C Interface Has Timeout Settings, Which Can Not Only Avoid Bus Locking, but Also Provide High-Speed Mode to Meet the Communication Requirements of up to 3.4 MHz.
All Features of INA219 Support Software Programmable.
Single Power Supply, Its Working Voltage Is+3.0to 5.5VBetween.

Product Description

 

 

INA219-40 c to + 85 c temperature range and can realize the maximum error of 1% accuracy, maximum offset of 100 uV.The advantage of the high precision of the product in combination with 12 resolution, can help clients as much as possible, reduce the pressure drop on the shunt resistor, which can minimize the power loss and power consumption, and saving board space.The device epic of 26 bus voltage range of 0 V to + V.
INA219 other important features include:
Calibration programmable registers can directly read its unit of measure is the ampere current, and power in watts per read.
For as many as 128 sampling averaging, in order to realize filter in noise environment.
The I2C interface has a timeout, not only can avoid the bus lock, but also can provide high-speed mode, meet the communication requirements of up to 3.4 MHz.
All features are support software programmable INA219.
Using single power supply, the working voltage between 3.0 to 5.5 V.
