• N channel vertical power MOSFET with charge pump, ground referenced CMOS patible input and diagnostic feedback, monolithically integrated in Smart SIPMOS technology.
• Fully protected by embedded protection functions Applications • µC patible high-side power switch with diagnostic feedback for 12V and 24V grounded loads • All types of resistive and capacitve loads • Most suitable for loads with high inrush currents, so as lamps • Replaces electromechanical relays, fuses and discrete circuits Basic Functions • Very low standby current • Improved electromagnetic patibility (EMC) • CMOS patible input • Stable behaviour at undervoltage • Wide operating voltage range Protection Functions • Reverse battery protection without external ponents (ReverSave) • Short circuit protection • Overload protection • Current limitation • Thermal shutdown • Overvoltage protection (not load dump) without external resistor • Loss of ground protection • Electrostatic discharge protection (ESD) Diagnostic Function • Proportional load current sense (with defined fault signal during thermal shutdown) Block Diagram Vbb IN1 IS1 IS2 IN2 Logic Channel 1 Channel 2 IN3 IS3 IS4 IN4 Logic Channel 3 Channel 4 GND Load 1 Load 2 Load 3 Load 4 Infineon technologies Page 1 of 1 2001-07-13 BTS737S2 Functional diagram IN1 IS1 .
