  • Forum Post: How to protect MCU from motor-induced current and voltage change?

    Anonymous Anonymous
    Hello, This is the first time we touch H-Bridge motor driver so there is a number of questions: How to isolate MCU and other IC from the motor control part, such that the sudden on and off of motor doesn't cause 1. Noise 2. Instability in other parts of the circuit? We have...

  • Forum Post: DRV8830: Battery for 1A current?

    Anonymous Anonymous
    Hi, I read from Motor Control and Drive Newsletter that TI has released DRV8830 and DRV8832 for battery powered applications. These two H-Bridges allow current of 1A . And since according to the newsletter they are targeted at battery powered applications, what battery do they use to provide...

    Hi, I think we are having a similar problem as reported in the post "DRV8432DKD cycle-by-cycle current limit" but I'm not sure why. We are using a DRV8432 in Dual full bridge mode. With the following: PWM frequency 1660Hz, 1uF bootstrap capacitors, 27kOhm OC-Adjust resistor value is...

    Hi Eric, Thanks for the answer. I am using exactly the same block diagram. I am measuring this current by the sense resistor with an ADC. 0.5A per motor, without charge, is so much current (for the motor model - a Faulhaber dc micromotor 2342), and I presume it has some relation with the driver...

  • Forum Post: DRV8801 VCP current?

    Michel Noxfeld Michel Noxfeld
    I'm using the DRV8801 to drive a DC motor at 10V, max current 1.5 A, no PWM. The motor is driving a gearbox with some load on it and we are testing the concept by driving the motor in a continuous cycle: Start Clockwise --> Delay --> Stop/Break using slow decay mode. Then same cycle again but...
