Step Load conditions

Hi,  in document 821801, in table 25, the slew rate dI/dt for device 028 is greater than for device 065. Is it correct or an error in document ? thanks and regards

    Hello Olivier, 

     

    A5E028B : stepload 2.5A , di/dt 100A/us

    A5E065B : stepload 3.5A, di/dt 70A/us

     

    di/dt is determined by how fast the current change, not how big the current step is. 

    Larger device A5E065B draws more total current, but draw it slower than smaller device A5E028B. 

     

    Notes to understand di/dt: 

    1- These are not linear scalings

    2- The numbers came from internal simulation and silicon characterization

     

    Conclusion : 

    Table 29 information is correct, not mistyped. 

     

    regards,
