BATTERY PROTECTION IC FOR 2-SERIAL TO 4-SERIAL-CELL PACK (SECONDARY PROTECTION)
S-8264A/B/C Series
 Precautions
• Do not connect batteries charged with V_CU + V_HC or more. If the connected batteries include a battery charged with
V_CU + V_HC or more, “H” may be output at CO after all pins are connected.
• In some application circuits, even if an overcharged battery is not included, the order of connecting batteries may be
restricted to prevent transient output of CO detection pulses when the batteries are connected. Perform thorough
evaluation with the actual application circuit.
• In the S-8264B Series, “H” may be output at CO after all the pins are connected. In this case, set the CTL pin from “L”
to “H”.
• Before the battery connection, short-circuit the battery side pins R_VDD and R1, shown in the figure in “ Battery
Protection IC Connection Example”.
• The application conditions for the input voltage, output voltage, and load current should not exceed the package power
dissipation.
• Do not apply to this IC an electrostatic discharge that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• SII claims no responsibility for any disputes arising out of or in connection with any infringement of patents owned
by a third party by products including this IC.
