Auxiliary motor control - 12 V DC motor controller
Infineon's comprehensive 12 V DC motor control portfolio offers cost- and energy-effective motor control solutions for automotive applications
Discover our versatile 12 V DC motor controller solutions for automotive applications. Brushed DC motors are easy to control, while brushless DC motors are smaller with less wear but require more advanced control algorithms. Explore our comprehensive portfolio of MOTIX™ motor control ICs and complementary products offered for optimized system solutions.
Advanced automotive 12 V DC motor controller solutions
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 less wear but need a complex control algorithm and, therefore, higher computing power than for a DC-brush motor drive. BLDC motors are most suitable for applications demanding long-term continuous operation time like fuel pumps.
Infineon is your one-stop shop for automotive motor control solutions, offering the industry's broadest portfolio of motor control ICs: Our MOTIX™ motor control IC portfolio comprises a range of solutions with varying levels of integration, from driver ICs to highly integrated system-on-chip (SoC) solutions. Every level has its own characteristic set of benefits.
Our scalable MOTIX™ product range is complemented by OptiMOS™ MOSFETs, OPTIREG™ power supply ICs, transceivers, microcontrollers (AURIX™, TRAVEO™, PSOC™) and XENSIV™ sensors.

They scale from current limit of minimum 10 A – 20 A. Typical application examples are door modules (i.e. door lock, e-charging lid) or the body and zone control modules.
DC and BLDC motors: Exploring their role in automotive motor control
MOTIX™ motor system ICs (SBC)
Infineon’s motor system ICs family is the world’s first IC to combine DC and BLDC motor control with functionalities such as power supply, CAN FD, and LIN. All devices of the MOTIX™ motor system ICs family feature a low-dropout voltage regulator with an output current of 250 mA/5 V, and they are available in a VQFN-48 (7 x 7 mm) packages.
Target applications involve Automotive DC motor control, for example seat control modules, power lift gate, sunroof module, seatbelt pretensioner as well as BLDC motor control such as fuel and water pumps, fans and transfer case.
Target applications:
- Automotive DC motor control (e.g., seat control modules, power lift gate, sunroof module, seatbelt pretensioner)
- BLDC motor control (e.g., fuel and water pumps, fans and transfer case)
System benefits:
- PCB savings up to 50 percent due to a unique integration approach
- Lower switching losses and EMC optimization due to adaptive MOSFET control
- Automatic regulation of MOSFET pre-charge currents diminishes the need for production MOSFET calibration
- VS monitoring in sleep mode activates the MOSFET to prevent from ECU damage when the motor is in generator mode
