Part Number: DS90UB929-Q1

Hi Madam/Sir,

for DS90UB929-Q1, in some application scenarios, we would like to disable it.

besides cut off the power supply for it, is there any other way to disable it?

Thanks a lot.

Hello Eric,

The most straightforward way to completely disable the 929 without powering off is to set the PDB pin = L. That puts the entire device into reset

Hi Casey,

Thanks for your comment.

Is there any side effect to set the PDB pin = L without power off the 929?

We intended to implement it.

Eric,

There is no side effect. PDB is supported as a power off/reset mechanism for the device with the power rails left high.

Best Regards,

Casey
