TDA4AEN-Q1: VTM default values

Daviel Almonte
Expert 3265 points
Part Number: TDA4AEN-Q1

Tool/software:

My customer is experiencing a reset during their Temp sweep test on the TDA4AEN. They believe that this is due to the VTM but we do not know if it is set to reset at -40 deg as Chapter 6
Device Configuration portion on the TRM is not completed. 

What temperature is the VTM set to reset the SOC?

    Daviel,

    VTM only asserts reset at the high end of the operating temp range, e.g., close to 125C.  The actual threshold is programmable, but there is no mechanism to create a reset for "lower than" a threshold.

    Regards,
