THVD8000: MODE Resistor

Part Number: THVD8000

Tool/software:

Hi experts,

May I know what's the reason we recommend to use 2Mohm for MODE? What would be acceptable range or any concern what if changing to other value? 

Thanks,

Allan

    Allan,

    We don't recommend you use a 2M resistor on the mode pin. The datasheet states there is a 2M ohm resistor on the mode pin (internal to the device).

    You should use a value much smaller than 2M to correctly bias the pin. The smaller the value, the stronger the biasing but the more leakage there will be. I would probably say 10k would be fine.
