    Hi Yingzhe,

    Thanks for reaching out to us, my name is Mamadou Diallo, I am the AE supporting low-side drivers.

    The minimum input voltage required to turn-on the driver is the Vih value that we specify and similarly the driver needs a 1V logic to take the driver state to a low state from a previous logic 1 state.

    The diagram below illustrates this:

    How is the customer planning on using our driver? How is Vih(max) and Vil(min) relevant to what the customer is trying to achieve?

    Thanks in advance for the clarification.

    Regards,

    -Mamadou
