Application Information
When excessive current flows due to output short-circuit or so, ringing occurs because of inductance between power source
line to IC, and may cause bad influences on IC operations. In order to avoid this case, connect a bypass capacitor across
IN terminal and GND terminal of IC. 1μF or higher is recommended.
Pull up /OC output by a resistance value of 10kΩ to 100kΩ.
Set up value which satisfies the application of either CL.
This application circuit does not guarantee its operation.
When using the circuit with changes to the external circuit constants, make sure to leave an adequate margin for external
components including AC/DC characteristics as well as dispersion of the IC.
