    Hi Ryan, Thanks for your reply. Our customers' EE is toothbrush. The space of PCB is limited. They have made their DRV8837EVM and plan to test. Here is their schematic. They use M_PWM1 to control both DRV8837. Will it still have the risk of shoot…

    Part Number: DRV8837 IN1 : PWM duty 80%, IN2 : PWM duty 0% / 400hz Why is the IN2 and OUT2 different?? I think the back EMF is a problem... right?

    Hi Ryan, With regards to the DRV8837C, I think the Rds has an additional role to play as well. The issue here is not only with the fast rise time but the fast charging of the coil, and I believe, the 8837C does not charge the coil as fast as the 8837…

    Gordon, Please see the following video: https://training.ti.com/motor-interfaces-and-pwm-frequencies Also, in section 7.3 of the datasheet there is a truth table. I would recommend operating the motor in either a drive state (CW or CCW) or a BRAKE state…

    Hi Vladislavas, It was confirmed that there is an issue with the spice model that is causing the spikes to appear at the output. Unfortunately, this is a problem that will not be able to be fixed at this moment. If you want to test and evaluate the DRV8837…

    ear Pablo, thanks for your reply. from drv8837 datasheet, in brake mode , both input1 and input2 should be high. but in complementary pwm mode ,i think that if input 1 is high, then input 2 should be low, vice versa. if it is this case ,i don't think…

    Hi user, To select the sense resistor, you need to determine a voltage across the sense resistor that, when amplified by a current shunt amplifier, the amplifier's output is acceptable voltage for the receiving ADC of an MCU (e.g. sense resistor sees…
