TPS92512HV: Power Sequencing and Design Questions for TPS92512HV

Part Number: TPS92512HV

Tool/software:

Hi,

I am using the TPS92512HV in a system where power is controlled by an interlock mechanism:

  • Power is disconnected when the interlock is triggered.
  • Power is reconnected when the interlock is released.

Could you help with the following:

  1. Are there specific precautions for power sequencing when power is reconnected?

  2. Is there a risk of reverse currents or transients on the LED output when power is disconnected? What protections are recommended?

  3. Are there any other key design considerations for stable operation in this setup?

Thanks,

Conor
