DRV8873-Q1: VM Operating Supply Current

Part Number: DRV8873-Q1

Hello,

I'd like to ask some questions about IVM - VM operating supply current of DRV8873S-Q1 under the other test conditions than those of data sheet.

  • Can the IVM values be different from what are specified in the data sheet if DISABLE = 1?
    • If they can be different, what will the values under DISABLE = 1 likely be?
  • How much will the IVM change (Min/Max values) over a VVM range from 10 to 16 V and the full temperature range (TA = -40 to 125 °C)?

Best regards,
Shinichi Yokota

    Hi Yokota-san,

    • Can the IVM values be different from what are specified in the data sheet if DISABLE = 1?
        • If they can be different, what will the values under DISABLE = 1 likely be?

    Yes, IVM can be different, but we do not have this data.

    • How much will the IVM change (Min/Max values) over a VVM range from 10 to 16 V and the full temperature range (TA = -40 to 125 °C)?

    We will investigate and reply by Tuesday.

    Hi Yokota-san,

    We are having difficultly locating the data. 

    Please expect the next reply by Friday.

    Hi Yokota-san,

    How much will the IVM change (Min/Max values) over a VVM range from 10 to 16 V and the full temperature range (TA = -40 to 125 °C)?

    The data shows the min could be as low at 3mA and the max as high as 5.5mA. Please note these are estimated values.
