BTS5440G
BTS5440G is Smart High-Side Power Switch manufactured by Infineon.
Description
- N channel vertical power MOSFET with charge pump, ground referenced CMOS patible input and technology. diagnostic feedback, monolithically integrated in Smart SIPMOS
- Providing embedded protective functions.
- Extern adjustable current limitation.
Application
- -
- - All types of resistive, inductive and capacitive loads µC patible high-side power switch with diagnostic feedback for 12 V grounded loads Due to the adjustable current limitation best suitable for loads with high inrush currents, so as lamps Replaces electromechanical relays, fuses and discrete circuits
Basic Functions
- Very low standby current
- CMOS patible input
- Improved electromagnetic patibility (EMC)
- Stable behaviour at low battery voltage
