Hi All:

TPS65983 internal integrated ADC, it can detect the current of PP EXT, but there is no detailed information on how to use it.

If I want to read the current of PP EXT through I2C interface:

1. Please provide detailed I2C timing.

2. Which register information needs to be read.

3. How to convert hexadecimal data returned by register into current value.

    Hello,

    You can read the current through the PP_EXT power path by reading bytes 9-10 of register 0x6A. You can reference the host interface technical reference manual for further details
