Other Parts Discussed in Thread: DRV8873
Hi team,
Here's some questions form the customer may need your help:
In hardware mode:
1. What is the minimum PWM duty cycle for the pwm control of 19KHZ to work properly? (Consider the effect of input and output delay)
2. The IPROPI pin resistance does not set the output maximum current, but simply provides a voltage variation of current? It's different from drv8873.
3. Enable the ITRIP feature via the nITRIP pin, maximum current setting of 6.5 A, 6.5 A has started protection, will 10 A overcurrent protection not be achieved? The OCP no longer works.
4. After OCP overcurrent protection, the output is turned off. Can I automatically restart? The motor starts with an inrush current of 12 A, the overcurrent protection shutdown output on start-up, will it fail to start?
Could you help check this case? Thanks.
Best Regards,
Cherry
