Submit Inventory List: Send the inventory list to the company's evaluation team via email or fax.

Professional Quotation: The company's professionals assess the inventory and provide a purchase quotation. Both parties reach an agreement.

Transaction Delivery: Agree on the specific transaction method and complete the delivery. Multiple settlement methods, including cash payment, are supported.

1，What is a smart power switch?

Smart power switches for automotive and industrial applications

A power switch is a high-performance semiconductor that controls the electrical circuit supplying power to a device. A smart power switch also offers advanced functionality such as power supply protection, load control and protection with diagnosis.

Infineon’s smart power switches portfolio consists of low and high-side switches available as single and multi-channel devices addressing a wide range of 12 V, 24 V, and 48 V automotive and industrial applications. Those switches can very well replace today's classic fuses and relays and offer additional advanced features, including diagnosis and current sensing, higher reliability, and restart possibility. They offer excellent protection against short-circuit, overcurrent, and overtemperature when driving different types of loads. With automotive qualifications and advanced features, Infineon's power switches are an ideal choice for automotive and industrial applications that require high performance, reliability, and support functional safety requirements.

2，High-side power switches for automotive and industrial applications

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. The PROFET™ family supports 12 V, 24 V, and 48 V automotive applications to replace classic fuses and relays by offering fast switching within µs, protection against overload, overvoltage, short-circuit, overtemperature, ground loss, and power supply loss. Additionally, different PROFET™ high-side power switch families can protect against dynamic overvoltage such as load dump and inductive load turn-off. The PROFET™ Guard family is the most advanced high-side smart power switch family addressing the latest needs in automotive power distribution.

3，Low-side power switches for automotive and industrial applications

Infineon's low-side smart power switches portfolio consists of two main product families: Classic HITFET™ and HITFET™ + for 12 V and 24 V automotive and industrial applications. HITFET™ family is Infineon's solution for smart low-side power switches. Their built-in intelligent protective features offer protection against overcurrent, overvoltage, short-circuit, overtemperature, and electrostatic discharge (ESD). The Classic HITFET™ offers high energy capability with RDS(on) range down to 10 mΩ. The HITFET™ + family comes in smaller package sizes with well-balanced short-circuit robustness, power dissipation in high-speed PWM applications, and diagnosis.

4，Multichannel power switches and controllers with SPI

Infineon's multichannel smart power switches and controllers with SPI portfolio support a wide range of automotive and industrial applications and consist of five main product families.

Infineon SPIDER products include multichannel SPI drivers for low-current loads such as LEDs, low-power bulbs, and stepper motors, providing a range of channels and configuration options.

The Infineon SPIDER+ family introduces enhanced performance and features with increased configuration capability. Both families are highly scalable in regard to PWM inputs and current capability.

The Infineon FLEX family is a fully scalable, multichannel, low-side power switch solution with SPI, integrated protection features, and advanced diagnosis.

Infineon SPOC™ +2 is the latest generation of high-side multichannel smart power switches with a serial interface and provides state-of-the-art diagnostic and protection features. It offers high flexibility with configurable features such as slew-rate control and intelligent restart strategy. Its SPI interface allows connecting of multiple devices via daisy-chain configuration to reduce the amount of GPIOs.
