  • LP5524 / CTRL input current at 5V

    Resolved
    Hi I'd like to expect the CTRL input current at ENA and ENB = 5V. I guess that ENA and ENB has internal pull down resistor and the input current should almost flow through the resistor, so the pull down resistor value should be around 1Mohm (1.2V/1…
