Tool/software:

Hi I would like to know if there is the tolerance of default delay time of bq27z746 hardware protection.

just like the picture shows, i would not change and keep the default delay time.

if the typical tOVP is 1000ms, what is the maximum tOVP and minimum tOVP?

and tUVP, tOCD, tOCC, tSCD?

Hello,

These delays are configurable, the min and max values for the delay times are shown in the calibration tab of BQStudio.

Regards,

Jonny.

Hello Jonny,

I know this can be configurable.

However, this parameter should have a range in the product specification. For instance, if the typical value is 1000ms, then what should be the upper and lower limits?

Hello,

We do not spec the variation from the configured value as you are requesting. We do however spec the step size for the delay, so +-1.953ms.

Regards,

Jonny.
