Hi,
In the datasheet of BQ24079, there are two places mentioned Vin(low), page 23 and 26. But there is no place to specify the value of the Vin(low). My first question is, what is the Vin(low) value and what is the Vin(low) loop?
My second question is, if I set the EN2=1, EN1=0, which means the input current limit is set by external resistor connected to ISET pin. what happens if the Vin drop below Vbat(reg) (4.1V for BQ24079)? The device should not get into DPPM mode because it is not USB100 or USB500 mode. is that right? What is about charging in this case? the fast-charge will stop or back to pre-charge?
Thanks,
