The device monitors both shunt voltage drop and bus supply voltage, with programmable conversion times and filtering. A programmable calibration value, combined with an internal multiplier, enables direct readouts of current in amperes. An additional multiplying register calculates power in watts. The I2C- or SMBUS-compatible interface features 16 programmable addresses.The INA219 senses across shunts on buses that can vary from 0 to 26 V. The device uses a single 3- to 5.5-V supply, drawing a maximum of 1 mA of supply current.This chip can be used in servers,telecom equipment,notebook computers,power management,battery chargers,welding equipment,power supplies,test equipment and so on.\n\nLibDriver INA219 is the full function driver of INA219 launched by LibDriver.It provides continuous mode reading, single mode reading, current acquisition, voltage acquisition and power acquisition.LibDriver is MISRA compliant.\n\n### Table of Contents\n\n  - [Instruction](#Instruction)\n  - [Install](#Install)\n  - [Usage](#Usage)\n    - [example basic](#example-basic)\n    - [example shot](#example-shot)\n  - [Document](#Document)\n  - [Contributing](#Contributing)\n  - [License](#License)\n  - [Contact Us](#Contact-Us)\n\n### Instruction\n\n/src includes LibDriver INA219 source files.\n\n/interface includes LibDriver INA219 IIC platform independent template.\n\n/test includes LibDriver INA219 driver test code and this code can test the chip necessary function simply.\n\n/example includes LibDriver INA219 sample code.\n\n/doc includes LibDriver INA219 offline document.\n\n/datasheet includes INA219 datasheet.\n\n/project includes the common Linux and MCU development board sample code.
