Description

The BTS840S2 is a N channel vertical power MOSFET with charge pump, ground referenced CMOS compatible input, diagnostic feedback and proportional load current sense monolithically integrated in Smart SIPMOS technology. The device can provide embedded protective functions. Applications of the BTS840S2 include μC compatible high-side power switch with diagnostic feedback for 12V and 24V grounded loads, All types of resistive, inductive and capacitve loads, Most suitable for loads with high inrush currents, so as lamps and Replaces electromechanical relays, fuses and discrete circuits. BTS840S2 Basic Functions • CMOS compatible input• Undervoltage and overvoltage shutdown with auto-restart and hysteresis• Fast demagnetization of inductive loads• Logic ground independent from load ground BTS840S2 Protection Functions • Short circuit protection• Overload protection• Current limitation• Thermal shutdown• Overvoltage protection (including load dump) with external resistor• Reverse battery protection with external resistor• Loss of ground and loss of Vbb protection• Electrostatic discharge protection (ESD) BTS840S2 Diagnostic Functions • Proportinal load current sense• Diagnostic feedback with open drain output• Open load detection in OFF-state with external resistor• Feedback of thermal shutdown in ON-state• Demultiplexing Capability• Multiple Input Enable for Easy Expansion• Typical Power Dissipation of 32 mW• Active Low Mutually Exclusive Outputs• Input Clamp Diodes Limit High Speed Termination Effects BTS840S2 Applications • µC compatible high-side power switch with diagnostic feedback for 12V and 24V grounded loads• All types of resistive, inductive and capacitve loads• Most suitable for loads with high inrush currents, so as lamps• Replaces electromechanical relays, fuses and discrete circuits
