Bit 7
THERMAL REGULATION:
0 = charger is in normal operation
1 = charge current is reduced due to high chip temperature
Bit 6
DPPM ACTIVE:
0 = DPPM loop is not active
1 = DPPM loop is active; charge current is reduced to support the load with the current required
Bit 5
THERMAL SUSPEND:
0 = charging is allowed
1 = charging is momentarily suspended because battery temperature is out of range
Bit 4
TERM CURRENT:
0 = charge termination current threshold has not been crossed; charging or no voltage at AC and
USB
1 = charge termination current threshold has been crossed and charging has been stopped. This
can be due to a battery reaching full capacity or to a battery removal condition
Bit 2..Bit1
CHG TIMEOUT, PRECHG TIMEOUT
0 = charging, timers did not time out
1 = one of the timers has timed out and charging has been terminated
Bit 0
BAT TEMP ERROR:
0 = battery temperature is in the allowed range for charging
1 = no temperature sensor detected
