s TREATMENT WHEN VOLTAGE MONITOR FUNCTION IS NOT USED
When the voltage monitor function is not used, connect the MSW1 terminal (pin 16) and MSW2 terminal (pin
17) to GND by taking their shortest ways and leave the VMON terminal (pin 15) open.

s NOTE ON VS TERMINAL
If the battery is charged through the body diode of the internal Pch MOS FET connected to the VS terminal (pin
5), the over-charge protection function cannot be disabled. Be careful not to apply a voltage equal to or higher
than the VCC terminal voltage to the VS terminal.
s NOTE ON ELECTROSTATIC APPLICATION
This IC has a built-in function to set ICC to 0 µA in power-down mode to extend the battery life. As a charger is
required to return the IC from power-down mode, use meticulous care not to let it malfunction, for example, with
applied static electricity. To prevent electrostatic noise from coming into each input pin of the IC, it is advisable
to lower impedance, for example, by adding a capacitor. The capacitor used for this purpose should be placed
as close to the IC as possible.
