Other Parts Discussed in Thread: TPS65981
Hi Team,
My customer would like to confirm a procedure to read real time current value on VBUS using ADCs 4cc command(in this case, they are using PP_EXT for VBUS path). They understand that as following procedure.
Could you double check if it's correct or not?
1. Write 0x3 to Data1 (0x09) (IPP_EXT (VBUS current) channel is "3")
2. Write 0x41444373 to Cmd1 (0x08) (ADCs = ASCII code: 0x41444373)
3. Read the value of bit [9: 0] of Data 1 (0x09), convert it to decimal number, and make it the value of ADC (dec)
4. Substitute ADC (dec) into the following equation and let the value of I be the current value
By the way, What should I assign to Isense_acc in equation (1)?
