Infineon Technologies Automotive Motor Control Solutions
Infineon Technologies Automotive Motor Control Solutions are used for the environmental and application requirements of the automotive industry. The requirements have influenced the replacement of mechanical solutions with electrical motors. High priority factors, like CO2 reduction, have increased the need for smart electrically controlled motors. The number of electrical motors in cars is growing steadily for classical combustion engines and electrical cars. Instead of using energy from a combustion engine, these solutions can be switched and speed controlled on demand.
Enablement of functionalities requires highly efficient, reliable, cost-effective, smaller, and flexible semiconductor solutions. Infineon enables those features with its comprehensive automotive motor control portfolio. Infineon can cover various application requirements with efficient and flexible solutions designed with low, medium, and high integration possibilities.
Infineon is constantly expanding its portfolio of semiconductors for smart, state-of-the-art DC and BLDC motor control applications. This broad portfolio of intelligent motor control ICs is complemented by microcontrollers, sensors, transceivers, and supply products for end-to-end solutions.
Low integration: Seats and centralized door locks
A low-integrated solution with discrete components gives you the flexibility to select the optimal device for each function.
Infineon’s TLE92108-x Multi MOSFET Driver ICs are designed to control up to eight half-bridges (up to 16 n-channel MOSFETs) with one packaged device.
Typical applications include seats and centralized door locks.
Medium integration: HVAC, mirror controls, & power lift gates

Medium-integrated devices combine gate drivers with the MOSFET power stage in a single package. A small PCB footprint, diagnostic feedback, and protection features add to the benefits of this integration concept. Fewer components also reduce qualification and manufacturing effort.
Typical target applications include HVAC blowers, HVAC flaps, mirror controls and power lift gates.
High integration: Window lift, sunroof, pumps, & fans

Infineon Embedded Power ICs are system-on-chip solutions integrating data processing, actuation, and sensing. Extensive diagnostics and protection features are embedded for high system reliability on a minimal footprint. All Embedded Power ICs are software-compatible and pin-compatible within the family, thus maximizing your design effort through scalability.
This platform includes solutions for both relay- and MOSFET-driven solutions targeted at DC and BLDC applications, e.g. for auxiliary pumps and fans, wiper, window lift, or sunroof.
Applications
Whatever you touch in a car, there is an electric motor close by. Brushed DC motors are easy to control and often serve as actuators with an overall short operating time. Torque control down to zero speed is easy to achieve.
Brushless DC (BLDC) motors have a longer lifetime but need a complex control algorithm. Therefore, they need higher computing power than a DC motor drive. BLDC motors are most suitable for applications demanding long-term continuous duty like fuel pumps.
