DRV120: Regarding DRV120

DRV103: Regarding DRV103

Part Number: DRV103

I want to use DRV103 IC for controlling the on/off of solonoid valves. Whether we need to provide the delay time for the controller to turn ON.

    Hi Joyson,

    Thank you for reaching out to the E2E forum!

    Would you be able to elaborate more on the delay you are talking about?

    If you are talking about the adjustable delay for the first 100% duty cycle before the device outputs PWM then that would be up to your design needs. If the delay is not necessarily important to you then you could leave the pin floating in which the device will have a delay of approximately 18us, which is caused by the internal circuitry. 

    Regards,
