DRV2667: Min Out Voltage

John Levy

Part Number: DRV2667

What is the minimum Vout[+/-] voltage of the DRV2667, I have  a colleague who insists that it is -Vbst, I think it is Vss. There is no clear answer from the data sheet.

    Hi, John,

    Welcome to E2E and thank you for your interest in our products!

    The DRV2667 outputs support voltage levels from Vss to VBST. Probably the confusion is related to the typical characteristics of the datasheet.

    https://www.ti.com/lit/ds/symlink/drv2667.pdf#page=9

    As you may see, the difference (OUT+) - (OUT-) can go from -100V to 100V. The maximum is reached when OUT+ = 100V and OUT- = VSS. The minimum is reached when OUT+ = VSS and OUT- = 100V.

    I hope this is clear. Please let me know if you have additional questions or comments.

    Best regards,
    Luis Fernando Rodríguez S.
