13-0 | In_13- In_0 | R | 0 | Bit Descriptions: Data conversion result. The I2C data transmission is a 2-byte transfer. Note that the conversion is done using a TI proprietary multi-slope integrating converter. 14-bit Data conversion result of current for port n. The update rate is around once per 100 ms in port powered state. The equation defining the current measured is: I = N × ISTEP Where ISTEP is defined below as well as the full scale value, according to the operating mode: |

Mode | Full Scale Value | ISTEP | ||||||
Port Powered and Classification | 1 A (with 0.255 Ω Rsense) | 61.035 µA | ||||||
Note: in any of the following cases, the result through I2C interface is automatically 0000 port is in OFF mode port is OFF while in semiauto mode and detect/class is not enabled port is OFF while in semiauto mode and detection result is incorrect In manual mode, if detect/class has been enabled at least once, the register retains the result of the last measurement |
