TPS65987DDK: About the TPS65987DDK internal power path OCP range

Bruce Dai
Intellectual 640 points
Part Number: TPS65987DDK

Tool/software:

Hi AE,

        I have two questions as follows

       1. For 5V/9V/15V at 3A, How to set the OCP threshold and response time ranges? Please provide upper and lower limits.

       2. For 5V/9V/15V at 2A, will the OCP threshold change? If yes, please provide its range and response time.

       3. What are the HW OCP threshold and response time ranges?

        

Best Regards

    Hello,

    Please be advised that the TPS65987DDK is not recommended for new designs.

    The OCP threshold is set by Maximum current settings.  The response time is not characterized or otherwise specified in the datasheet.  There are no upper and lower limits.

    Yes.  The Maximum current settings should be updated accordingly.  The response time is not characterized or otherwise specified in the datasheet.  There are no upper and lower limits.
