Tool/software:
Hi,
I am trying to turn on both the FETs (CHG and DSG) via the FET_CONTROL direct command and sending 0x3 as the data byte. Below is the wave form of the communication:
As mentioned in the reference manual I have already set the HOST_FETON_EN and HOST_FETOFF_EN bits, via the FET_OPTIONS (0x901E) command and verified the same via a read-back of the register.
I have also read the Battery_Status (0x12) to ensure SS and SA both are zero and no other abnormalities are present. But still the FETs fail to turn ON. Is there any prerequisite or a particular sequence I am missing out on?
