Other Parts Discussed in Thread: BQSTUDIO, BQ27742EVM, EV2400
I'm currently working on BQ27742, I achieved shutdown mode using this. I wanted to try Full Sleep mode. I tried different methods as mentioned in reference manual. But, not successful in achieving current as mentioned in datasheet. The methods which I followed are below,
1. Sleep current=15mA, FS wait=0, entered manually into full sleep by giving FULL_SLEEP command.
2. Sleep current=1mA,FS wait=5, tried to see whether Full sleep is achieved automatically.
Not achieved required current. Sometimes, when I used 1st point I achieved full sleep current, but not always. And the current is varying for every second. Not as mentioned in datasheet for every 20secs. And the range of current is 65uA - 300uA for every 2 secs.
How can I achieve Full sleep?
Thanks in advance,
