Part Number:DRV8323
Hi, I had a fatal problem with DRV8323 driver. I applied 10kHz PWM (open-loop) pulse with 50% duty cycle to each phase. The operation reach to approximate 200mA. After 3 minutes operating without load, the DRV8323 explored.
I retry with another DRV8323 but only after 1 minute, the temperature of it reach to over 50 celcius degree.
The MOSFET I used is csd19532ktt with 44nC gate charge.
The attached file is my schematic.
Please help me, thanks a lot.
