Bit 7 DISABLE ISINK AT AC (disables an internal current sink from pin AC to GND)
0 = 60 μA current sink enabled when no input voltage at pin AC detected
1 = 60 μA current sink disabled
Bit 6..5 POWER PATH DPPM THRESHOLD1/0:
00 = 3.5 V
01 = 3.75 V
10 = 4.25 V
11 = 4.50 V
Bit 4 PRECHARGE TIME
0 = pre-charge time is 30 min
1 = pre-charge time is 60 min
Bit 3..2 TERMINATION CURRENT FACTOR1/0:
00 = 0.04
01 = 0.1
10 = 0.15
11 = 0.2
Bit 1 CHARGER ACTIVE:
0 = charger is not charging
1 = charger is charging (DPPM or thermal regulation may be active)
Bit 0 DISABLE ISINK AT USB (disables an internal current sink from pin USB to GND)
0 = 60 μA current sink enabled when no input voltage at pin USB detected
1 = 60 μA current sink disabled
Note: There is a current sink on pins AC and USB which is activated when there is no voltage detected at
the pin and Bit7 or Bit0 in CHCONFIG3 are set to 0. This is implemented in order to avoid the pins to
be floating when not connected to a power source. The current sink is disabled automatically as soon
as an input voltage is detected at the pin.
