bq24190 VSYS

Other Parts Discussed in Thread: BQ24190

Hello,

Our customer checking   bq24190 function and performance by the datasheet, and they have a question.

About VSYS, in the datasheet p.16, it is describe that when the charging is disabled or terminated, the system is always regulated at 150mv above the minimum system voltage setting.

 On the other hand, in p.34, the explanation for Bit 0 of Register REG08, it is written that 0- Not in VSYSMIN regulation(BAT > VSYSMIN).

So, they say that the description of p.16 is not correct , it has to be deleted a word "always".

Because when the charging has finished, BAT voltage is higher than VSYSMIN voltage and in that case VSYSMIN regulation will not happen.

Is the customer understandings correct ?

Thanks and best regards,

Hiro
