Application Information

When excessive current flows owing to output shortcircuit or so, ringing occurs by inductance of power source line to IC,

and may cause bad influences upon IC actions. In order to avoid this case, connect a bypath capacitor CIN by VIN terminal

and GND terminal of IC. 1μF or higher is recommended.

Pull up /OC output by resistance 10kΩ ~ 100kΩ.

Set up value which satisfies the application as CL and Ferrite Beads.

This system connection diagram doesn’t guarantee operating as the application.

The external circuit constant and so on is changed and it uses, in which there are adequate margins by taking into account

external parts or dispersion of IC including not only static characteristics but also transient characteristics.
