Part Number: UCC27211
Other Parts Discussed in Thread: LMG1210,

Tool/software:

Could you please take a look at what the parameters of the UCC27211 and LMG1210 marked in red circles are? We didn't find it.

    Hey,

    Thank you for reaching out to TI with your questions regarding the UCC27211 and the LMG1210.

    I do not see any parameters marked in red circles. Is there supposed to be an image attached here?

    Thank you,

    William Moore

    Hey,

    The output stage pullup and pulldown resistances for the devices are not directly specified in the datasheet but can be derived using V=IR and the following specs.

    UCC27211 datasheet spec:

    For example, R_LOL can be derived from V_LOL = 0.07V typical and  I_LO = 100mA to get R_LOL typical = 0.7 Ohms under this operating condition.

    Here is the datasheet spec for the LMG1210 also:

    Let me know if there are any questions.

    Thank you,

    William Moore
