DRV8873-Q1: motor operation

Part Number: DRV8873-Q1

Hello.

1. For development reasons, the CPU firmware cannot be changed.

If you select from the output waveform of the CPU, it will be "Independent Mode".

Is there anything wrong with using "Independent Mode" with "H-Bridge"?

(Connect both ends of the motor to OUT1 and OUT2.)

 

 

2. If I don't use the "IPROPI1/2" pin, what should I do with the "IPROPI1/2" pin?

3. Is there a problem with controlling PWM in INDEPENDENT mode in specifications?

 

Best Regard

  • Moriyama-san,

    1)  As long as the customer follows the truth table in the datasheet and it matches the desired operation from an application standpoint, there is no problem here.

    2)  Connect to GND

    3)  No problem.  Similar answer to #1.  Device will behave as truth table.  Output will follow input.
