Hi,
I'm currently working on bq27742 fuel gauge. It is having default design capacity-1000mAh, design voltage-3.8v stored in flash. My battery spec is 4.2v,2150mAh.
1. Can you tell me, what all the parameters I need to change, if I change these two parameters.
2. If I make SLEEP bit as 0 in register and SHUTDOWN command not used, is there any way to make PMIC enter low current state.
Thank in advance,
Kavya.
Hello Kavya,
This gauge has many settings and it will depend on your application what needs to be changed.
The most common are:
There is no way for the gauge to enter lower power states if you disable sleep. You can see this in section 2.7 Power Modes of the TRM in the flow chart.
Sincerely,
Wyatt Keller
