At 12V my 2. At 7V the current at stand still is more than 1.
L Datasheet pdf – DMOS DUAL FULL BRIDGE DRIVER – ST Microelectronics
So I suppose I have to limit the current, but I am not sure how. The datasheet mentions an integrated PWM current control but I can’t find any further information on how to use it.
It explains how to the overcurrent protection can be used to roughly regulate the load current what I have tried, it works but the motor then runs choppy and I feel sorry for it. I think you may have selected the wrong part for what you are trying to do. Without any extra circuitry, the L will only provide voltage-mode control. You can reduce that by reducing the duty cycle, but if you want to have something that will control current for you, an L might be better suited:.

You can reduce that by reducing the duty cycle, but if you want to have something that will control current for you, an L might be better suited: Daniel 5, 12 You could, p6206 pulsing the IN input is more common.
It changes how the motor current will decay during the off-cycle slightly. I tried pulsing enable with 1, 4 and datashee kHz, it did not work well and the motor was running very rough.

Pulsing IN with 15 kHz seems to work very datashdet though. Sign up or log in Sign up using Google. Sign up using Facebook.
