BATTERY PROTECTION IC FOR 3-SERIES OR 4-SERIES CELL PACK
S-8204B Series
Rev.3.6_00
8. CTLC pin and CTLD pin
The S-8204B Series has two pins to control.
The CTLC pin controls the output voltage from the COP pin, the CTLD pin controls the output voltage from the DOP
pin. Thus it is possible for users to control the output voltages from the COP pin and DOP pin independently. These
controls precede the battery protection circuit.

Caution Note that when the power supply fluctuates, unexpected behavior might occur if an electrical
potential is generated between the potentials of "H" level input to the CTLC pin / the CTLD pin and
IC's V_DD by external filters R_VDD1 and C_VDD1.
