DRV8313: DRV8313 About V3P3 output at sleep mode of EVM

Part Number: DRV8313

Hi,

I have a question about V3P3.
I use DRV8313EVM.

I confirmed that V3P3 is eneble at VM power-on (not connect USB), nSlEEP/nRESET is Low.
I saw TP2.
Why is V3P3 enable?

Maybe, i think that V3P3 is disable at sleep mode from datasheet.
But there is the difference between datasheet and my bench.

Best regards,
Shimizu

Hi Shimizu-san,

Sorry for the confusion. V3P3 remains operating when nSLEEP is set to 0.

Table 3 of the datasheet is incorrect and will be updated.

Hi Rick,

Thank you for your support.

I understand that DRV8313 outputs V3P3 with UVLO disable by supplying VM.
Is it correct?

Best regards,
Shimizu
