I am currently trying to use the motor driver MC33926 to power a brushed motor but for some weird reason it is not working even though the motor driver seems to be outputting some voltage at OUT2. Here is my setup:
VIN (on the left of the motor driver) - +12V from a battery that is delivering roughly 1.5A
GND (on the left) - -12V from that same battery.
OUT2 - hooked to the brushed motor.
OUT1 - hooked to the other end of the brushed motor.
VIN (on the right of the motor driver) - left alone since it is internally connected to the left VIN
GND (on the right of motor driver) - left alone since its interally connected to the GND on the left
Vdd - 3.3V from my microcontroller
IN2 - LOW (I wired it to the GND pin on this motor driver)
IN1 - HIGH (I wired it to the Vdd pin on this motor driver)
PWM/D2 - I wired this pin to a PWM output pin from my microcontroller
PWM/D1 - LOW by using a jumper
SF - not used
FB - not used
EN - HIGH
SLEW - HIGH
INV - HIGH
I did this setup similar to the example that pololu wrote on MC33926’s product page but it does not work. Is there something wrong with my wiring? I tried changing the INV pin LOW/HIGH and the IN2 IN2 to LOW/HIGH etc but it still does not work. I know for a fact that my brushed motor is not broken because when i hooked that same 12V batter directly to the motor, it runs perfectly but when I put it through this motor driver, it does not work. Can someone with experience with this motor driver help me please because my project is due soon! Thanks in advance.
