TPS92692-Q1: How to detect an open LED in the TPS92692

Hello expert,

I need your help. I’d like to know how to implement open-circuit diagnostics for the TPS92692. My plan is to use an MCU to detect whether the LED load is open-circuited by monitoring the voltage at the IMON pin. However, I’ll also be using PWM dimming functionality. If PWM dimming is enabled, how can I still accurately perform LED open-circuit detection? Could you please share some ideas?

Thanks!
