current.

<Under-voltage Lockout (UVLO)>

in order to protect the battery charger, the UVLO circuit keeps the charger in shut-down mode when the voltage between the

input pin voltage and BAT pin voltage falls to less than 30mV. The charge will not restart until the voltage between the input pin

voltage and BAT pin voltage rises more than 100mV. During shut-down mode, the driver transistor turns off but a failure

detection circuit operates, and supply current is reduced to 8μA.

<Soft-Start Function>

To protect against inrush current from the input to the battery, soft-start time is optimized and internally set (150μs, TYP.).
