12description: |
13  The RTQ6056 is a high accuracy current-sense monitor with I2C and SMBus
14  interface, and the device provides full information for system by reading
15  out the loading current and power.
16
17  The device monitors both of the drops across sense resistor and the BUS
18  voltage, converts into the current in amperes, and power in watts through
19  internal analog-to-digital converter ADC. The programmable calibration,
20  adjustable conversion time, and averaging function are also built in for
21  more design flexibility.
