High-side switches are used to turn electrical loads ON and OFF by switching the positive (high-) side of the load supply. Additionally, smart high-side switches are designed with the ability to protect themselves and diagnose possible unintended system behavior.
The PROFET™ family is Infineon's solution for power switch ICs. PROFET™ stands for PROtected MOSFET and gathers all high-side switches, including automotive qualified and products for industrial use. PROFET™ intelligent high-switches consist of DMOS power transistors and CMOS logic circuitry to form a device with integrated driver functionality, protection, and diagnostic features.
Infineon’s extensive portfolio of PROFET™ smart high-side power switches is clustered into a variety of product families that are supported for a wide range of applications. With state-of-the-art diagnostics and protection features, PROFET™ devices can switch loads in a wide current range including cost optimized solutions, for loads below 1 A (e.g. LED loads) up to loads of 40 A (e.g. PTC heater) using the newest low RDS(on) high current switches.
High-Side Switch Product Portfolio
Infineon’s PROFET™ protected high-side MOSFET power switches offer solutions for a wide range of automotive and industrial applications and are available as single and multi-channel switches. Our latest DMOS transistor technologies offer improved short circuit robustness and better performance as well as high voltage capability and optimized chip size.
All PROFET™ smart high-side power switch families offer protection against overload, overvoltage, short-circuit, excessive temperature, ground loss, power supply loss, and Electrostatic Discharge (ESD). Additionally, the different PROFET™ high-side load switch families can protect against dynamic overvoltage such as load dump and inductive load turn-off depending on the application they were designed for (e.g. automotive, industrial, consumer, commercial, construction, and agricultural vehicles (CAV)).
PROFET™ includes several families:
