High Side Switches for Industrial Applications
All Industrial PROFET™ devices are extremely energy robust, making them ideal for switching inductive loads and driving relays. Their main application areas include high-voltage applications up to 58V, high-speed PWM applications (up to 1kHz) and they are most notably capable of switching higher inductances smoothly. The well-established core devices can be driven at temperature ranges of -30…85°C, the new Industrial PROFET™ family even offers an extended temperature range of -40…1 25°C. The product concept includes a variety of protection functions like over temperature, short circuit, overload, current limitation, open load detection and is available with diagnosis.
PROFET™ stands for protected MOSFET and the product family includes all High Side switches, whether they are automotive qualified or designed for the needs of industrial applications. PROFET™ intelligent power switches consist of DMOS power transistor and CMOS logic circuitry for complete built-in protection. They are highly integrated load switches and incorporate a broad range of smart features, including diagnosis and protection.
All PROFET™ sub-families offer protection against overload, overvoltage, short-circuit, excessive temperature, ground loss, power supply loss and Electrostatic Discharge (ESD). Additionally, depending on the applications they were designed for (automotive, industrial, consumer, transportation and commercial vehicles ...), the PROFET™ load switch subfamilies can also protect against dynamic overvoltage such as load dump and inductive load turn-off.
SPIDER products are highly integrated multichannel SPI driver for small current loads, such as relays & solenoids, LED’s, small bulbs and stepper motors. SPIDER devices are designed for automotive and industrial applications with dedicated feature sets. The SPIDER family (TLE72x) consists of 4 and 8 channel low-side and 8 channel low-side/ high-side drivers with 2 configurable channels. For more information, please follow this link.
SPOC™+2 is the new generation of multichannel smart high-side power controllers for automotive and industrial applications based on SMART7 technology. Control, configuration and diagnostics are carried out via Serial Peripheral Interface (SPI). The family offers four and six channel devices (from 5.5mΩ to 70mΩ) in PG-TSDSO-24 exposed pad package and provides state of the art diagnostics and protection features. Body control modules (BCM), in-car ECUs like junction, fuse and relay boxes now start to become increasingly complex, therefore the flexibility of SPOC™+2 with a number of new features is the right solution.
FLEX is Infineon´s Multichannel SPI Low-Side Power Switches family for powertrain, safety and industrial applications is specially designed to drive a various range of loads from relays, injector valves, oxygen probe heater and general purpose solenoids, up to uni-polar stepper motors.
TEMPFET™ devices are temperature protected FET-switches. The TEMPFET Switches can be controlled as any discrete FET, but in addition, they implement a temperature protection. Characteristic for TEMPFET™ devices is the temperature sensor. Because of the way the temperature sensor is connected, the classic TEMPFET™ devices are restricted to applications with slower switching times. With the Speed-TEMPFET™ family the temperature sensor is externally available. This enables the user to define the device’s reaction to overtemperature, but also enables the use of Speed TEMPFET™ for fast-switching PWM applications.

Ever increasing demand for highly integrated protected switches will continue to drive the use, acceptance and development of HITFET™ (High-Integrated Temperature protected FET) long into the future. HITFET™ low-side switches are versatile power transistors ideally designed for automotive and industrial applications. Their built-in intelligence and protective features offer not only significant cost and PCB reduction, shorter time to market, but also improved performance & reliability over conventional, discrete solutions.

Galvanic Isolated High Side Switches and Input ICs
The ISOFACE™ ISO1H8xxG product family offers robust and intelligent galvanic isolated interfaces between the micro-controller or bus-ASIC and the power switches. Its 8-channel high-side switches can drive any kind of resistive, inductive or capacitive loads.
ISOFACE™ high side switches integrate robust galvanic isolation (UL508 and EN 61131-2 certified) to protect the 3.3V/5V control domain of an industrial control system from the harsh 24V (typ.) process side and 8-channel high-side power-switching capabilities of up to 1.2A per channel. Further features like active current limitation, over temperature protection and common diagnostic feedback for over temperature and for Vbb under-voltage make them the ideal choice for industry automation systems.
The ISOFACE™ product family is best suited for applications such as Programmable Logic Controllers (PLC), Distributed Control Systems, General Control Equipment, Robotics and Solid State Relay. The ISO1H81xG products enable OEM-product designs which meet the stringent EMI requirements of the IEC 61131-2 norm (zone C) applicable for Programmable Logical Controllers (PLC).
