Cautions 1. The above connection example will not guarantee successful operation. Perform thorough
evaluation using the actual application.
2. A pull-down resistor is included in the CTL pin. To perform overheat protection via the PTC in
the S-8264A Series, connect the PTC before connecting batteries.
3. When the power fluctuation is large, connect the power supply of the PTC to the VDD pin of the
S-8264A Series.
4. Since “H” may be output at CO transiently when the battery is being connected, connect the
positive terminal of BAT1 last in order to prevent the three terminal protection fuse from cutoff.
