Hi All expert :
My customer have 2 new E-bike projects want to use bq77915, but currently bq77915 protection level can not achieve their target.
Could you help to check whether we can achieve their target ?
-. X portion just follow datasheet currently spec, don’t need to change.
-. Customer generally use 3m/5m/10m rsense
-. Currently these project didn’t kick off yet, if TI can follow customer requirement, please share the spec to me I will discuss with customer before developing new IC.
