Hi,
Does datasheet have explain about MR function detail?
I have read "9.3.23 Manual Reset Timer and Reset Output ( MR and RESET)", but can't understand the time sequence.
If I pull MR pin to low, it enter to Hi-Z mode, right?
How do I leave the Hi-Z mode?
Need set any register or pull what pin to active the BQ25120? I can't use I2C command to BQ25120 after I pull MR pin to low.
Thanks!
Jeff
Hi Jeff,
You set /CD pin low to enter HiZ mode on battery only. The /MR pin is used for button functions only.
To exit HiZ mode, you drive /CD pin high or VIN is plugged in. Thereafter I2C is active.
Here is a document that also has FAQs on this device which you might find useful.
