Bit name and function | USB power | AC power | USB power enable | AC power enable | AC input current MSB | AC input current LSB | USB input current MSB | USB input current LSB |
Default | x | x | 0 | 0 | 1 | 1 | 0 | 1 |
Set by signal | ||||||||
Default value loaded by: | UVLO | UVLO | Voltage removed at AC OR UVLO | Voltage removed at AC OR UVLO | Voltage removed at USB OR UVLO | Voltage removed at USB OR UVLO | ||
Read/write | R | R | R/W | R/W | R/W | R/W | R/W | R/W |
Bit 7 | USB power:
0 = USB power is not present and/or not in the range valid for charging 1 = USB source is present and in the range valid for charging. B7 remains active as long as the charge source is present |
Bit 6 | AC power:
0 = wall plug is not present and/or not in the range valid for charging 1 = wall plug source is present and in the range valid for charging. B6 remains active as long as the charge source is present |
Bit 5 | USB POWER ENABLE
0 = USB power input is enabled 1 = USB power input is disabled (USB suspend mode) |
Bit 4 | AC POWER ENABLE
0 = AC power input is enabled 1 = AC power input is disabled |
Bit 3..2 | AC INPUT CURRENT
00 = input current from AC input is 100 mA max 01 = input current from AC input is 500 mA max 10 = input current from AC input is 1300 mA max 11 = input current from AC input is 2500 mA |
Bit 1..0 | USB INPUT CURRENT
00 = input current from USB input is 100 mA max 01 = input current from USB input is 500 mA max 10 = input current from USB input is 800 mA max 11 = input current from USB input is 1300 mA max |
Note: safety timers are cleared if the input voltage at both AC and USB are removed. |
