TPS3808: Vsense supply sequence

Shota Mago

Part Number: TPS3808

Hi team,

My customer will use TPS3808 and provided a question.

Is it okay that Vsense pin voltage applied before VDD?

The customer is not sure if it's okay or not since Vsense and VDD ramps simultaneously in the timing diagram of the datasheet.

Best regards,

Hi Shota San

It will work if VDD and Vsnse rams up together.

Delay time will increase, in case if VDD is starting from 0V.

Hi Trailokya-san

Thanks for your quick reply.

Sorry for confusing.

The customer would like to know if it's okay or not Vsense voltage is applied under condition that VDD=0V.

Is it acceptable for the device?

Best regards,

There should not be any issue if customer applies sense when VDD= 0.
