bsp75n issue 4 - september 2006 5 www.zetex.com ? zetex semiconductors plc 2006 application information the current-limit protection circuitry is designed to de-activate at low v ds to prevent the load current from being unnecessarily restricted during normal operation. the design max dc operating current is therefore determined by the thermal capability of the package/board combination, rather than by the protection circuitry (see graph on page 7 'typical output characteristic'). this does not compromise the products ability to self protect at low v ds . the overtemperature protection circuit trips at a minimum of 150c. so the available package dissipation reduces as the maximum required ambi ent temperature increase s. this leads to the following maximum recommended continuous operating currents. minimum copper area characteristics for minimum copper condition as described in note (c) max. ambient temperature t amb maximum continuous current v in = 5v v in = 10v 25c @ v in = 5v 720 840 70c @ v in = 5v 575 670 85c @ v in = 5v 520 605 125c @ v in = 5v 320 375
