BSP75N 60V self-protected low-side IntellifetTM MOSFET switch Summary Continuous drain source voltage VDS=60V On-state resistance 500m Maximum nominal load current(a) 1.1A (VIN = 5V) Minimum nominal load current(c) 0.7A (VIN = 5V) Clamping energy 550mJ SOT223 Description Self-protected low side MOSFET. Monolithic over temperature, over current, over voltage (active clamp) and ESD protected logic level functionality. Intended as a general purpose switch. S S D IN Features Note: The tab is connected to the source pin and must be electrically isolated from the drain pin. Connection of significant copper to the drain pin is recommended for best thermal performance. * Short circuit protection with auto restart * Over-voltage protection (active clamp) * Thermal shutdown with auto restart * Over-current protection * Input protection (ESD) * High continuous current rating * Load dump protection (actively protects load) * Logic level input Ordering information Device Reel size (inches) Tape width (mm) Quantity per reel 7 12mm embossed 1000 BSP75NTA Device marking BSP75N Issue 4 - September 2006 (c) Zetex Semiconductors plc 2006 1 www.zetex.com BSP75N Functional block diagram D Over voltage protection dV/dt limitation IN Human body ESD protection Over current protection Logic Over temperature protection S Applications * Especially suited for loads with a high in-rush current such as lamps and motors. * All types of resistive, inductive and capacitive loads in switching applications. * C compatible power switch for 12V and 24V DC applications. * Automotive rated. * Replaces electromechanical relays and discrete circuits. Linear mode capability - the current-limiting protection circuitry is designed to de-activate at low Vds, in order not to compromise the load current during normal operation. The design maximum DC operating current is therefore determined by the thermal capability of the package/board combination, rather than by the protection circuitry. This does not compromise the products ability to self protect itself at low VDS.

() Protection features may operate outside spec for VIN<4.5V. () Integrated protection functions are designed to prevent IC destruction under fault conditions described in the datasheet. Fault conditions are considered as "outside" normal operating range. Protection functions are not designed for continuous, repetitive operation. Issue 4 - September 2006 (c) Zetex Semiconductors plc 2006 4 www.zetex.com BSP75N Application information The current-limit protection circuitry is designed to de-activate at low VDS 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 VDS. The overtemperature protection circuit trips at a minimum of 150C. So the available package dissipation reduces as the maximum required ambient temperature increases. This leads to the following maximum recommended continuous operating currents.
