2. Under Voltage Locked Out (UVLO) Circuit

UVLO is the circuit for preventing malfunction of the switch by voltage variation.

In the Power Up : less than 3.5 V (typ.) and in the Power Down : less than 3.3 V (typ.)

OUT : OFF

FLG : “L” ( = 0V)

3. Behavior in the case of Power ON

This IC is slowly started up by Soft-Start Operation when IC is powered on.

This function is to prevent from flowing large current in the period of charging the capacitor which is connected to

Output-pin.

In Power ON state, Soft-Start Time is 5ms (typ.)
