About

Advanced automotive 12 V DC motor control 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.

Automotive motor control solutions from Infineon combine high-quality products with software, tools and services to streamline development and accelerate time-to-market.

MOTIX™ gate driver ICs give the ECU designer high flexibility

The MOTIX™ Driver portfolio provides a wide  range of gate driver ICs to select from for both brushed DC motors and brushless DC motors for 12, 24 or 48 V applications.

MOTIX™ multi MOSFET gate driver ICs for BDC motors are designed to control up to eight half-bridges (up to 16 N-channel MOSFETs) with one packaged device. Outstanding low quiescent current, advanced protection, and diagnostic features make the product family an optimal solution for automotive applications like seat and power liftgate control and various use cases in body control modules (BCM), such as centralized door lock or washer pumps.

The MOTIX™ gate driver ICs for BLDC motors portfolio comprises of automotive AEC-Q100 qualified 3-phase gate driver ICs for 12 to 48 V applications. It offers a range of options, including variants with and without integrated current sense amplifiers, and meets different safety and reliability requirements, from QM to fully ISO 26262-compliant devices, ensuring a high level of functional safety in automotive applications.

Achieve cost and energy efficiency in auxiliary motor control

MOTIX™ single half-bridge ICs offer integrated high-current motor drivers with PWM capability, overcurrent protection, adjustable slew rates, and logic-level input. They can form an H-bridge or three-phase bridge with an additional MOTIX™ single half-bridge IC and provide overtemperature shutdown and current sense capability.

MOTIX™ multi half-bridge ICs are protected half-bridge drivers designed for automotive applications like small DC motors for flaps in HVAC and mirror adjustment. They handle up to 0.9 A per output, diagnose issues, and support 3 to 12 half-bridges with PWM.  MOTIX™ TLE9166EQ for door control offers a versatile solution for door control modules and is suited for door locks, safe locks, mirror fold and adjustment, mirror heating, electrochromic mirrors, incandescent bulbs, and LEDs. 

MOTIX™ BTM90xx full-bride ICs are ISO 26262-ready and represent a cost-optimized product family of four variants that can be selected based on various application targets. 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. 

For BDC & BLDC motors: System IC integrating LIN or CAN communication

Infineon’s MOTIX™ motor system IC (SBC) 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 IC (SBC) family feature a low-dropout voltage regulator with an output current of 250 mA/5 V. The communication interface incorporates a CAN FD transceiver up to 5 Mbit/s according to ISO 11898-2:2016 (including Partial Networking (PN) option) and/or LIN transceiver. All devices are available in a VQFN-48 (7 x 7 mm) packages.

MOTIX™ TLE9563/4 for brushless DC (BLDC) motor control applications, such as 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
