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