Cautions
1. The above connection example will not guarantee successful operation. Perform thorough evaluation using the actual
application.
2. Apull-down resistor is included in the CTLpin. To perform overheat protection via the PTC in the uP8206A/P Series,
connect the PTC before connecting batteries.
3. When the power fluctuation is large, connect the power supply of the PTC to the VDDpin of the uP8206A/P Series.
4. Cell connections: To prevent incorrect output activation, the VSS pin must be connected first. Connect sequences
must be used as following:
4-series cell configuration
BAT4 J BAT3 J BAT2 J BAT1
3-series cell configuration
BAT3 J BAT2 J BAT1
2-series cell configuration
BAT2 J BAT1
