DRV8303 VDD_SPI current draw

Jessica Riley1

Hello,

Can you please tell me what the maximum expected current draw is on the VDD_SPI input? The datasheet lists the maximum voltage allowed on this pin but doesn't give the current supply requirements.

Thanks!

Hi Jess

VDD_SPI is only to supply the SDO output which is similar to a internal pull up and consumes very little current. Choose the level the same as your MCU logic level and 5mA capability will be enough with margin.

VDD_SPI current will depend on the impedance present on SDO.
