Charging Current Control

As shown in the typical application circuit, the

AIC1782 offers two open-drained output pins,

ICOA and ICOB pins, to control the charging cur-

rent of battery pack A and pack B. When fast

charge is completed, the AIC1782 enters the

trickle charge mode. In trickle charge mode, the

ICOA or ICOB pins output switch with predeter-

mined duty cycle. Refer to the table of trickle

charge mode (TABLE 6), the duty cycle is deter-

mined by the setting of SEL1 and SEL2 pins. The

following table summarizes how ICOA and ICOB

pins correspond to various charging states.

Test Mode

Fig. 5 shows the timing diagram for externally

controlled ADJ, ABV, BBV, ATS, BTS, SEL1 and

SEL2 pin voltages of a recommended AIC1782

test scheme, utilizing TEST mode function. Out-

put waveforms of LEA1, LEA2, LEB1, LEB2,

ICOA and ICOB of a properly functioning

AIC1782 are also shown in the figure. For de-

tailed information please consult with AIC staffs

directly.
