DRV8243-Q1: Fast decay on PH/EN mode

Kei Kuwahara

Part Number: DRV8243-Q1

Hello team,

DRV8243-Q1 datasheet on p.34 states as below:

I just want to confirm will this feature ( auto dead time) work on PH/EN mode with fast decay (switching to opposite FET pairs)?

I am afraid that 4 FETs turn on and huge penetration current might destroy the IC.

Hi Kuwahara san

Thank you for your questions.

>>I just want to confirm will this feature ( auto dead time) work on PH/EN mode with fast decay (switching to opposite FET pairs)?

Yes. DRV generate automatically the optimal dead time on PH/EN mode with fast decay. No shoot through happens.4FETs does not turn at the same time.
