BATTERY PROTECTION IC FOR 3-SERIES OR 4-SERIES CELL PACK
S-8204A Series
8. CTLC pin and CTLD pin
The S-8204A Series has two pins to control output voltage.
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.

*4. The status is controlled by the voltage detection circuit.
Caution Note that when the power supply fluctuates, unexpected behavior might occur if an
electrical potential is generated between the potentials of "L" level input to the CTLC pin
/ CTLD pin and IC's VSS by external filters RVSS and CVSS.
