Part Number: DRV8353F Tool/software: There is a layer on the gate off signal. This seems to be causing a short. Is there a way to eliminate it?
Yellow (C1): High side Gate-Gnd voltage
Green (C2): Low side Gate-Gnd voltage
Part Number: DRV8353F Tool/software: I want to verify the gate driver output signal (Vgs) with all switching elements removed. Please recommend register setting to prevent output deactivation due to fault occurrence.
Hi Vincent,
After review I do not believe the regenerative voltages should cause much issue in the driver itself as that current path returning through the FET body diodes should be tolerable. However, I am still not confident that there will be no abnormalities…
Hi Matt!
Please find my comments below:
Matt Calvo said: There are many various grounds mentioned throughout the datasheet (i.e. GND, AGND, PGND, BGND, & DGND). Can you please help to clarify what all of the grounds signify and whether any specific precautions…
Hey Itamar,
Sorry for the delay.
A MTBF/FIT estimator tool is available on ti.com ( link ). . Simply enter a part number in the tool and customers get an estimated FIT rate calculated by TI’s internal reliability testing of grouped silicon technology.…
Part Number: DRV8353F Hello
i am wondering if drv8353f has SPI IT-mode. I am asking this since some MCU provide SPI setting with IT-mode and no further parameter adjustment is needed.
Thank you
Mirza
Hi Joshua,

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…
