BQ24075-Q1: BQ24075QRGTRQ1-Turn on issue with no Vin and Battery connected

Hi Anthony

This is a battery operated hand held Unit, when it is being shipped we do not want battery to be drained.

We thought of controlling the battery charge and discharge through SYSOFF instead of other options.

Thanks n regards

Hi Krishna,

That's a great application for the SYSOFF pin. Does my suggested solution help answer your question?

Anthony

SySOFF is supposed to be controlled through GPIO not External Vin. The reason is in cases where Raw Power is off and system is switched and upon switch on through Battery GPIO will not be able to pull it low till boot up and initialisation happens.

Hope a larger problem of controlling SySOFF is seen as it goes to high impedance state internally.

Thanks n regards
