PRODUCTION DATA
To set the input voltage limit, write a 16-bit InputVoltage register command (REG0x0B/0A()) using the data format listed in Figure 9-26, Table 9-33, and Table 9-34.
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).
