The charger provides charge voltage range from 1.024 V to 19.200 V, with 16-mV step resolution. Any write below 1.024 V or above 19.200 V is ignored. Upon POR, REG0x15() is by default set as 4192 mV for 1 s, 8400 mV for 2 s, 12592 mV for 3 s or 16800 mV for 4 s. After CHRG_OK, if host writes REG0x14() before REG0x15(), the charge will start after the write to REG0x14().If the battery is different from 4.2 V/cell, the host has to write to REG0x15() before REG0x14() for correct battery voltage setting. Writing REG0x15() to 0 will set REG0x15() to default value on CELL_BATPRESZ pin, and force REG0x14() to zero to disable charge. The SRN pin is used to sense the battery voltage for voltage regulation and should be connected as close to the battery as possible, and directly place a decoupling capacitor (0.1-µF recommended) as close to the device as possible to decouple high frequency noise.
