TPS92662-Q1: TPS92662, pwm dimming change, LED fault trigger.

Part Number: TPS92662-Q1

Hi~

In TPS92662, LED fault trigger happen during PWM dimming duty change(fade in, fade out) mode.

But when check LED cell voltage, it doesn't hit any LED open or short threshold voltage, but just LED fault register trigger.

Does TPS92662 check LED short or open during pwm dimming off time? or how can I understand this abnormal symptom?

Need your advice.
