DRV8871: What is Iout (VILIM) variation of DRV8871 at 2A output?

Part Number: DRV8871

 Hello guys,

 One of my customers is considering using DRV8871 for their new products.

 They have the following questions about DRV8871. Could you please give me your reply?

Q1.  Iout (VILIM) variation of DRV8871 at 1A output is shown in 6.5 Electrical Characteristics

on page5 of the device datasheet as the follow.

 

  We need Iout (VILIM) variation (Min,Typ,Max) at 2A output and -40~+85 degree C. Do you have any data? Or is it same as 1A output case?

Q2. Was the following data taken with 1A Iout and +25 degree C? Do you have any graph or data at 2A output case?

      Or is it same as this graph?

  

 Your reply would be much appreciated.

 Best regards,

 Kazuya.

     Hello guys,

     I can't attach graphs.

     For Q1, 6.5 Electrical Characteristics says that VLIM min=59kV, typ=64kV and max=69kV.

     For Q2, they asked about Figure 2, VILIM vs Temperature graph on page 6.

     Best regards,

     Kazuya.

     Hello,

    Q1:   We need Iout (VILIM) variation (Min,Typ,Max) at 2A output and -40~+85 degree C. Do you have any data? Or is it same as 1A output case?

    A:     You can expect the same variation with 2A output and -40~85C

    Q2:   Was the following data taken with 1A Iout and +25 degree C? Do you have any graph or data at 2A output case? Or is it same as this graph?

    A:     The data was taken at 1A but you can expect the same data for 2A output case.
