Tool/software:
We are incorporating multiple TPS1663 6A eFuse for use in either a 12V or 24V truck vehicle control system. We will be using 11 devices each with a worse case 5A load are concerned about surviving a load dump pulse define in your document snoaaa1. Note we can operate up to 3 outputs simultaneously creating a 15A current requirement. We are planning to use a DM8W36AQ TVS at the input of each of the 11 TPS1633 eFuse components. It seems with all 11 TVS components effectively in parallel then a 200V pulse with a source resistance of 0.1ohm would result in a max current in each TVS of about 145amps or a short wattage pulse of of about 5800watts. These numbers appear to be within the TVS specs. Is this design approach feasible. Any feedback is appreciated.
