Figure 27. Over Duty Protection
ODP=35% setup
(*1) â¦PWM < 35% : Turn on in relevant CH of same time PWM_DutyH.
(*2) â¦PWM > 35% : An LED of relevant CH is turn off by PWM_DutyH=35%.
(*3) â¦PWM=H signal beyond 35% is changed, and that doesn't react to IC in particular.
(*4) â¦PWM > 35% : An LED of relevant CH is turn off by PWM_DutyH=35%.
(*5) â¦ODP Function= ON : When a PWM signal is equivalent to 100%, LED=OFF continues after 35 %.
(*6) ⦠When the next PWM=H signal is input, an LED is also turn on at the same time.
