The CHGSTATUS register contents indicate the status of charge.
Bit 7 - USB charge:
0 = inactive.
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 charge:
0 = wall plug source 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 - Thermal suspend:
0 = charging is allowed
1 = charging is momentarily suspended due to excessive power dissipation on chip.
Bit 4 - Term current:
0 = charging, charge termination current threshold has not been crossed.
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 3 - 1 Prechg Timeout, Chg Timeout, Taper Timeout:
If CHCONFIG<5>=0: Bit 3 equals the output of the taper voltage comparator directly, without any timer delay.
If CHCONFIG<5>=1: there is a delay of 30 minutes because the timers have to time out first.
0 = charging, timers did not time out
1 = one of the timers has timed out and charging has been terminated.
Bit 0 - BattTemp error: Battery temperature error
0 = battery temperature is inside the allowed range and that charging is allowed.
1 = battery temperature is outside of the allowed range and that charging is suspended.
B1-4 may be reset via the serial interface in order to force a reset of the charger. Any attempt to write to B0 and
B5-7 is ignored. A
1
in B<7:0> sets the INT pin active unless the corresponding bit in the MASK register is set.
