Design solutions for integrated automotive engine control systems for pumps and fans

Whether electric or fuel-powered, luxury or economy class, vehicles today are equipped with increasingly more systems that rely on a wide range of motor control applications. This commonly includes powertrain applications like auxiliary pumps and fans, electric pumps such as fuel pump, oil pump and water pump, and fans like HVAC blower, engine or battery cooling fan.
Recent growth in vehicle electrification has resulted in greater dependence on microelectronic components. Besides the existing challenges, the addition of more and advanced microelectronic components inside the car and strict emission regulations  have brought new challenges for automotive pumps and fans applications:

1. Car manufacturers face the challenge of accommodating a growing number of auxiliary pumps for several thermal management cycles, such as for battery cooling,    in a limited space.
2. An increasing number of electric components inside the car requires more power.
3. Due to their location near the engine, motor control solutions for automotive pumps and fans must be highly robust and able to withstand high temperatures.
4. Automakers are looking for solutions to increase fuel efficiency and reduce carbon dioxide (CO2) emissions further to meet the emission regulations.

offers different system solutions to overcome these challenges and meet customer-specific preferences. Infineon´s extensive offering of intelligent motor control ICs is complemented by microcontrollers, sensors, transceivers, voltage regulators and MOSFETs to simplify the design of end-to-end system solutions and different integration levels are offered based on different customer needs. Integrated system on chip solutions, known as 32-bit motor control SoC, can deliver a best-fit set of functions to address these applications, especially for 12 V.
