APPLICATION INFORMATIONS
THE AIC1782 OPERATION
Power-on and Battery Prequalifying
The AIC1782 is a sequential charger, initiating a
charge action on either battery pack A or B.
When power is first applied to the AIC1782, all
internal digital circuit of the AIC1782 are reset
by the internal power-on-reset circuitry, the out-
put of LED‘s (depending on the setting of SEL1
and SEL2 pins) flash 3 times to indicate the ini-
tiation of power-on. If both battery pack A and B
are present when V
CC
is applied to the AIC1782,
the charge action begins with battery pack A if
conditions are acceptable.
Condition of battery pack A is examined through
the ATS and ABV pins, while battery pack B is
examined through the BTS and BBV pins. The
acceptable limits of ABV and BBV are deter-
mined by the input voltage of SEL3 pin and the
acceptable temperature sense voltage window
for ATS and BTS are 0.29 V
CC
to 0.72 V
CC.
The AIC1782 controls the initiation of a charge
action and checks for acceptable battery volt-
age and temperature prior to fast charging. If
the voltage of ABV or BBV fail to fall within the
predetermined acceptable limits, the corre-
sponding battery pack enters a charging-
suspending mode. If the voltage of ATS or BTS
is outside the 0.29 V
CC
to 0.72 V
CC
window, ac-
tion to AIC1782 is determined by the input volt-
age of SEL3 pin.
