DRV8353RH-EVM: Dead time problem

Part Number:DRV8353RH-EVM

Hi,

We started evaluation tests with DRV8353RH-EVM evaluation board

According to DRV8353RH data sheet, the Gate drive dead time, tDEAD is 100nS typical

We measured much higher: 264nS and 157nS, see two pictures below:

 

 

Those values will significantly reduced performance of our high-performance motor drivers

How we can get dead time as low as possible (100nS maximum with DRV8353RH)?

Please advice, this is very urgent issue

Best regards,

Zeev Kogan
