Tool/software:
Hello.
I am John.
I am designing a BLDC motor drive with DRV8350H.
I am writing this because I have a question about the circuit design.
My product receives PWM speed command from an external MCU and operates a BLDC motor based on the hall sensor signal.
Q1. VDRAIN voltage is 48V, can I input 48V as VM power?
Q2. Can I connect the low side FET source to GND?
Q3. Can this design be operated with square wave six-step BLDC motor control?
Q4. If SOA, SOB, SOC of DRV8353H shunt resistor type are not connected to an external MCU, is the motor control characteristic the same square wave 6-step control as DRV8350H?
Can it not be operated with FOC control?
Q5. Below is my circuit diagram. Please let me know if there is any error.
