LM5110: clamping body diodes

Dylan Lumborg

Part Number: LM5110

Would you please advise if clamping body diodes are present on the OUT_A and OUT_B pins? i.e. if the device is unpowered will the outputs be clamped to a diode drop from 0V?

Thanks

    Hi Dylan,

    Thanks for reaching out to us, my name is Mamadou Diallo, I am an applications engineer with the High Power Drivers group.

    Figure 17 of the driver's datasheet models the output stage where the body diodes of Q1 and Q2 help clamp the output of the driver and prevent damage from undesired negative transients.

    Please let us know if you require further assistance or press the green button if this helped address your concerns.

    Thanks.

    Regards,

    -Mamadou

    Hi Mamadou,

    Thanks for this clarification. I just wanted to be sure that this figure was correct as I could not see any details in the electrical specifications tables.

    Thanks for your help.
