Hi Joshua,
Joshua Maize said: Does this fault shutdown the external mosfet operation when flagged?
The MOSFET was not driven successfully, and the temperature of the pre-driver rose sharply and was damaged.

Hello experts,
I am currently using the driver DRV8353FH to power an H-bridge circuit, thus, only drivers A and B are being used. I am currently having an issue with the current amplifiers.
- I have placed shunt resistors as stated…
Hey Max,
It seems like the power stage is getting the correct voltages.
Have you checked INHA to ensure that the pwm signals are being sent? And also please check if the hall signals are being sent / commutating correctly as well.
I would need to look…
Hi Vikas,
Regenerative braking in 1xPWM mode is possible but will require all lowside MOSFETS to be HI-Z'd st once which is not possible if taking the Hall states directly back to the pins for sensing in the driver.
A workaround is to route the Hall…

Hey Aitor,
I have one small update/caution regarding the turn on/off times desired: For most applications we suggest keeping the turn on/off time between 100-200nS and never really driving the MOSFET gates with the maximum IDRIVE due to ringing/parasitics…
Part Number: DRV8353F Is it possible to use the DRV835xF for a DCDC full bridge power converter instead of a three-phase inverter?
This entails using only four of the available six driving channels that the device can provide.
If this is the case, do…
Hi Yesaiahu,
Sorry for the delay again.
