TPS53667: Clear_fault command

Given Ding

Part Number: TPS53667

Hi Team，

Want to check on behavior of clear_fault command.

To my understanding，it will clear all fault currently，but if the fault is still there，when reading fault register again，the fault but will be set again，right？

Hi Travis,

Thanks for your reply.

one more questions, all the fault Reg can only be cleared using Clear_fault command, right?

if just read, it cannot be cleared automatically, right？

if just re-cycle EN, then all fault REGs will also be cleared except for PRE_OVP , right? But if the issue still exist, then read Fault REG, it is still report, right?

Thanks.

Hi Given,

That's correct. Reading the faults will not reset them, and cycling EN will reset all faults except PRE_OVP.

Thanks,

Travis
