PRODUCTION DATA.
To set the input voltage limit, write a 16-bit InputVoltage register command (REG0x0B/0A()) using the data format listed in Table 33 and Table 34.
If the input voltage drops more than the InputVoltage register allows, the device enters DPM and reduces the charge current. The default offset voltage is 1.28 V below the no-load VBUS voltage. The DC offset is 3.2 V (0000000).
