Part Number: DRV8833
Hi, I'm about to use the DRV8833CPWPR.
This is my current schematic. I use the 9V battery to power the motor driver.
I use CC3200 QFN MCU's PWM pins to control this.
My questions are,
0) The CC3200 operates with 3.3 volts. I've connected the nSLEEP pin to the CC3200's GPIO.
If I set the nSLEEP GPIO pin to high, which is 3.3V, does the motor driver runs (not sleeping)?
I can't find the threshold voltage value of nSLEEP pin to make the motor driver run.
1) Regardless of the value of AIN/BIN, is there no output when the nSLEEP pin is set to low?
The CC3200's GPIO pins start at HIGH after it is powered on. This causes the motor to run after the power is on.
So I hope to add a strong pull-down resistor (2.7k Ohm) at the sleep pin to use it as an "ENABLE" pin, instead of adding 4 pull-down resistors on each PWM pins.
If the nSLEEP pin is low, does the output of DRV8833 goes off?
2) Lastly, this motor driver causes heat. So I think this chip has to be apart from the CC3200 Wi-Fi MCU.
Is there a recommended "keep-out" distance when placing the DRV8833?
