Note If Over current detect circuit is operated, FLG-pin is Low-Level and over current limit circuit is operated. At

this time, output's operation is as followed.

µPD16855A/B : output is OFF and Flg-pin is High-Level when CTL-pin is non-active level.

µPD16855C/D : output synchronizes in Flg-pin = “L”, and is OFF.

Flg-pin is High-Level when CTL-pin is non-active level.

And then when CTL-pin turns to active level again, if UVLO and TSD are not operated, Output-pin is reset

to ON-state.
