Other Parts Discussed in Thread: CSD19535KTT
Hi Team, seeking for some assistance
Used TIDA-00281 reference design for my BLDC motor. in this schematic i have used LDO instead of buck regulator.
when i start BLDC motor with 48VDC supply. we gradually increase duty cycle from 10% - 80% and 80% - 10% the motor is run fine in CW and ACW direction. in this test condition i didn't sense phase current.
here, i have attached PWM waveform.
After some time suddenly motor stop running and MOSFET was damaged also my gate driver IC (phase-C) damaged.
