Part Number:BQ25601
Hello,
I am using BQ25601 as charger IC (no OTG mode) with I2C control.
I would like to understand behavior of SYS pin voltage
1) Through REG01 register we can set SYS voltage.
2) If I use SYS voltage as 3.5V, does it mean as mention in figure 15 that during charging when battery voltage is below 3.5V, VSYS is maintained at 3.6V when battery voltage is above 3.5V, VSYS will follow battery voltage. So VSYS will gradually rise from 3.6V to 4.2V.
3) If no charging is in progress and battery voltage (VBAT) is between 3 to 3.5V then how much will be the voltage on SYS pin?
