BSP75N 60V SELF-PROTECTED LOW-SIDE INTELLIFET 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) Clamping energy SOT223 0.7A (VIN = 5V) 550mJ 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 www.slkormicro.com 1 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. www.slkormicro.com 2 BSP75N Absolute maximum ratings Parameter Symbol Limit Unit Continuous drain-source voltage VDS 60 V Drain-source voltage for short circuit protection VIN = 5V VDS(SC) 36 V Drain-source voltage for short circuit protection VIN = 10V VDS(SC) 20 V Continuous input voltage VIN -0.2 ... +10 V Peak input voltage VIN -0.2 ... +20 V Operating temperature range T j, -40 to +150 °C Storage temperature range Tstg -55 to +150 °C Power dissipation at TA =25°C (a) PD 1.5 W Power dissipation at TA =25°C (c) PD 0.6 W Continuous drain current @ VIN=10V; TA=25°C (a) ID 1.3 A Continuous drain current @ VIN=5V; TA=25°C (a) ID 1.1 A Continuous drain current @ VIN=5V; TA=25°C (c) ID 0.7 A Continuous source current (body diode) (a) IS 2.0 A Pulsed source current (body diode) (b) IS 3.3 A Unclamped single pulse inductive energy EAS 550 mJ Load dump protection VLoadDump 80 V Electrostatic discharge (human body model) VESD 4000 V DIN humidity category, DIN 40 040 E IEC climatic category, DIN IEC 68-1 40/150/56 Thermal resistance Parameter Symbol Limit Unit Junction to ambient (a) R⍜JA 83 °C/W Junction to ambient (b) R⍜JA 45 °C/W Junction to ambient (c) R⍜JA 208 °C/W NOTES: (a) For a device surface mounted on 25mm x 25mm x 1.6mm FR4 board with a high coverage of single sided 2oz weight copper.
