TPS564201: What if a -12V is applied to TPS564201

Part Number: TPS564201

Hi team,

My customer is using TPS564201 and the project is in MP stage. But in the test process in the production line, customer mistakenly apply a -12V to TPS564201 input and the -12V input last for 2mins.

So with a -12V input for  2mins, will the device 100% get damaged or it may have a chance to survive in the -12V condition without any damage? Thanks.

Best regards,

    Hi Wayne,

    When a negative voltage is applied to the input pin, there should be negative current flow from GND to Vin pin through internal body diodes.

    If no current limit on the negative voltage, there is a risk that IC may be damaged or it can survive but its reliability may be affected.
