TPS2546: Use Fault Pin control EN pin

Part Number: TPS2546

Dear Team,

May I know if we could use Fault# pin to drive EN pin low when the over current condition occur? 

Thank you.

Regards,

Jim 

  • Hi Jim,

    This is not necessary as the TPS2546 will automatically open the internal power path when it detects an overcurrent condition. The FAULT pin is used to notify a downstream device. You can look at Figures 20 through 22 in the datasheet for the devices behavior in this specific condition
