DRV8303: Question about start-up of DRV8303

Hiroyasu Matsubara

Part Number: DRV8303

Hello,

I would like to ask about start-up of DRV8303.

On the document , DRV8303 datasheet,8.8.1,
would you please tell me, why the SH_x pin voltage at start-up should be less than 8.5V,
the reason is to prevent any malfunction anywhere ?

Regards,

Hey Matsubara-san,

Yes, the reason we have SHx be below 8.5V during start up is to ensure proper device operation and to prevent malfunction of the driver.

Best,
Akshay
