Hello, I have a question about the current being drawn through my motors when hooked up to the DRV8833. If I connect the motor directly to my battery (3.7-4.2 V LiPo), I pull about 1.2 A, which is about what I need. When I connect through the motor driver, I only pull about 0.8 A, which is not giving me quite enough power for my application. For testing the maximum current output I am not using a PWM signal for the motor input channel, I just have A1 hooked up to VIN and A2 to ground.
Is the lack of current simply a limitation of the motors I have chosen or is there something I can do to draw the current I need? The 0.4 amps really makes the difference in my application. I can run the circuit with a 2 cell lipo at around 8v, but then I run into the opposite problem, the motors try to draw too much current and end up barely spinning, which i’m guessing is a result of the drv8833 attempting to protect the circuit from too much current.
