BQ25155: BQ25155 reset button behavior

Part Number: BQ25155
Other Parts Discussed in Thread: BQ25150,


i would like your feedback about this scenario with BQ25155 or BQ25150.

As reported in the manual:

it seems that we can change the reset behavior.

In our project, the bq25155 is configured at the boot up in such way to generate an hw reset after 14 seconds.

Under some specific condition (battery voltage very low), I want to disable this behavior, by having no action after 14 seconds (see the picture below).

I ran some tests in these conditions:


- battery voltage is very low (< 2Volts);

- VIN present;


- the button MR is always detected as low;

- the hw reset keeps on happening after 14seconds from the boot;

- the device re-boots continuously after the hw reset because VIN is present;  


It seems that it not possible to disable the hw reset in the condition described above.

Could I kindly have a feedback from you please ?

Thanks in advance !
