Part Number: DRV8302 Hi team,
Here's an issue from the customer may need your help:
After power-up, the chip is not able to startup properly, the measured pin DVDD, AVDD,GVDD are all 0V. The customer would like to know what's the possible reason for…
Part Number: DRV8302 Hi Experts,
DRV8302 outputs nFUALT pin when the fault condition occurs. One of the condistion is DVDD_UV or DVDD undervoltage which is triggered when DVDD undervoltage condition occurs. What is the UVLO voltage for DVDD?
Regards, …
Part Number: DRV8302 Hi team,
Here's an issue from the customer may need your help:
If the PowerPAD is not properly connected to GND, would the device be not able to operate normally when EN_gate is pulled high? GH_X and GL_X are always 0 V? Thanks…
The problem was with the EN_GATE pin. When this pin is set to high all the voltages GVDD, AVDD, and PVDD appear, although EN_GATE pin is only responsible for enabling the gate of driver and current shunt amplifier.
Thanks.

Part Number: DRV8302 Hi,
Good Day. I have a customer who is working with DRV8302. Please see below his query for your reference. Thank you very much.
I'm using the DRV8302DCAR to drive FETs in a motor controller. My motors require 5-10Amps, and the DRV8302…
Hi Elizabeth, I finally had some time to run bench testing with DRV8301/DRV8302 in regards to seeing nFAULT behavior occur without much explanation. Going back to the original issue:
