Hello
I made a board as DRV8301 kit.
My DRV8301 board can output PWM signals when the chip of DRV8301 is paded, but then begin to fault, the status register said : GVDD_UV.
I change the DRV8301 with a new chip, it working well at the first time, but then it go to fault : GVDD_UV. Why?
My DRV8301 board has the same problems as follows:
EN_GATE=1; EN_GATE=0
GVDD: 1.33V 0V
DVDD: 3.3 V 0V
AVDD: 6.6 V 0V
PVDD: 16 V 16V
My schmatic is as follows:
