Automotive Fans & Pumps by Infineon

A rising dependency on microelectronic components has been a trend, especially for small motors that deliver up to 1 kW, in which integrated system-on-chip solutions are being used for electric pumps, such as a fuel pump, oil pump, water pump, and fans like a HVAC blower and engine cooling fan.

Owing to their proximity to the engine, motor control solutions for automotive pumps and fans must be highly robust, and able to withstand high temperatures. Additionally, the need to accommodate a rising number of auxiliary pumps in a limited space is a challenge.

Applications

Pumps

When it comes to pumps, enhanced motor control efficiency is of absolute priority. Our cost and system optimized solutions, boasting a high level of integration, aim to do exactly that, especially those designed for BLDC motor control.

Infineon’s large and scalable product portfolio are tailored to high performance and budget requirements - both discrete and highly integrated solutions will help you save system cost and provide maximum motor control efficiency.

With solid industry know-how, Infineon’s solutions for applications like electric water pump and fuel pump ensure high performance, fuel efficiency, and increased lifetime.


Fans

With fans and HVAC systems, stable RPM and low mechanical noise are crucial factors. Also, the right product portfolio goes a long way in ensuring robustness and reliability of the system.

Infineon's broad product portfolio addresses a variety of cooling fan and HVAC applications. It enables high reliability due to the extensive diagnostics and protections which are embedded within the System-on-Chip. At the same time, it is possible to control the consumed energy due to intelligent power saving modes.
