OPERATIONAL EXPLANATION (Continued)

<Flag function>

The flag circuit is built in which monitors the state of the power switch.

The FLG pin outputs Low level when the reverse current prevention function is operating. A resistance of 10kΩ to 100kΩ is

recommended for the FLG pin pull-up resistance.

Auto recovery type (product type C)

Protective function

FLG pin Low level output

Return to FLG pin High level output

Current limiter
