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.
