Resistance should be as small as possible to avoid lowering of
the overcharge detection accuracy caused by VDD pin current.

Select a resistance as large as possible to prevent large current
when a charger is connected in reverse.
*5
*1. If the threshold voltage of an FET is low, the FET may not cut the charging current.
If an FET with a threshold voltage equal to or higher than the overdischarge detection voltage is used, discharging
may be stopped before overdischarge is detected.
**2.
If the withstanding voltage between the gate and source is lower than the charger voltage, the FET may be destroyed.
*3. If R1 has a high resistance, the voltage between VDD and VSS may exceed the absolute maximum rating when a
charger is connected in reverse since the current flows from the charger to the IC. Insert a resistor of 300
Ω or higher
to R1 for ESD protection.
*4. If a capacitor of less than 0.022
μF is connected to C1, DO may oscillate when load short-circuiting is detected. Be
sure to connect a capacitor of 0.022
μF or higher to C1.
*5. If R2 has a resistance higher than 4 k
Ω, the charging current may not be cut when a high-voltage charger is
connected.
Caution 1. The above constants may be changed without notice.
2. The DP pin should be open.
3. It has not been confirmed whether the operation is normal or not in circuits other than the above
example of connection. In addition, the example of connection shown above and the constant do not
guarantee proper operation.
Perform through evaluation using the actual application to set the
constant.
