What integration levels do BLDC motor driver ICs offer?

Infineon's MOTIX™ BLDC motor driver portfolio spans gate driver ICs (12 V–60 V), motor system ICs (SBC), and fully integrated motor control SoCs/SiPs. Each tier trades flexibility for integration - from discrete gate driving to single-chip solutions combining a microcontroller (MCU), gate driver, and power stage.

Infineon offers one of the industry's most comprehensive brushless DC (BLDC) motor driver portfolios, with three hardware integration tiers plus a software layer. Each tier suits a different balance of design flexibility, bill-of-materials (BOM), and board space:

  • MOTIX™ Driver | Gate driver ICs -cover a 12 V–60 V system voltage range and give the designer maximum flexibility: the driver stage is external, allowing the most suitable customized MOSFETs to be paired with it for a specific automotive or industrial target application.
  • MOTIX™ SBC | Motor system ICs - integrate a 2-phase or 3-phase motor gate driver, power-management functions, and a communication interface such as LIN or CAN FD within a single device. By combining these functions in one package, they reduce external component count, PCB area, and overall bill of materials (BOM).
  • MOTIX™ MCU | Motor control system-on-chip (SoC) and system-in-package (SiP) devices - integrate an Arm® Cortex®-M microcontroller, voltage regulator, LIN or CAN FD transceiver, and the driver stage for brushed DC (BDC) or brushless DC (BLDC) motor control on a single die (SoC) or in one package (SiP). Some fully integrated variants also add the power stage (MOSFETs), enabling the most compact designs.

MOTIX™ Software

The MOTIX™ software tier is distinct from the three hardware tiers above: it comprises the MOTIX™ MCU peripheral driver, an AUTOSAR-compliant Complex Device Driver, and motor control software, qualified to industry standards. Some components can be licensed for productive automotive use.

Selecting between tiers is a trade-off, not a hierarchy: a gate driver IC gives the most design freedom at the cost of more external parts, while an SoC/SiP minimizes footprint and BOM at the cost of flexibility. Application-specific guidance for automotive and industrial/consumer use cases follows below.

Which BLDC motor drivers suit automotive use cases?

Infineon's AEC-Q100-qualified MOTIX™ BLDC motor drivers address 12 V and 48 V automotive architectures. They cover applications from electric power steering and brake-by-wire (safety and chassis) to coolant pumps and HVAC fans (thermal management), 48 V mild-hybrid electric vehicle (MHEV) starter-generators (powertrain) and seat control (body applications).

Brushless DC (BLDC) motors are increasingly replacing brushed DC motors in automotive systems because they offer higher efficiency, longer service life, and improved reliability, while eliminating brush wear and brush-generated electrical noise. 

Typical automotive BLDC applications:

  • Safety & chassis (12 V and 48 V) – electric power steering (EPS), brake boosters, steer-by-wire, brake-by-wire, active suspension, and transfer-case actuation.
  • Thermal management (12 V and 48 V) – coolant pumps, oil pumps, valves, radiator fans, HVAC blowers, and battery thermal-management systems.
  • Powertrain (48 V) – starter-generators for MHEV systems, e-turbos, electric superchargers, and transfer-case actuators.Functional safety capability is one of the key differentiators 

Functional safety capability is one of the key differentiators

Looking at the MOTIX™ gate driver ICs for BLDC motors, the ASIL D-qualified TLE9189QVW addresses electric power steering (EPS) and braking systems, while the ASIL B-qualified TLE9186QVW targets cost-sensitive thermal management and body-control applications. As another example, the ASIL B-qualified MOTIX™ motor control SoCs and SiPs are ideal for safety-relevant thermal management and body applications where a compact, highly integrated motor driver solution is essential.
Beyond functional safety, customers can select the most appropriate device based on voltage range, diagnostic capabilities, integration level, and specific application requirements.

Which BLDC motor driver fits power tools and service robots?

MOTIX™ gate driver ICs and system-in-package (SiP) solutions for industrial and consumer applications operate from battery supply voltages up to 70 V. They target power tools, robotic lawn mowers, vacuum cleaners, and light industrial drives that need a compact form factor, high efficiency, and flexible MOSFET gate drive.

Demand for efficient, high-performance electric motors in battery-powered equipment continues to grow. Infineon's battery-supplied BLDC gate drivers and motor controllers serve professional and consumer power tools, service robots such as vacuum cleaners and robotic lawnmowers, and light industrial drives including small servo drives, HVAC fans, and pumps.

Stand-alone gate driver ICs

The MOTIX™ 6EDL7151 and 6EDL7141 are 3-phase gate driver ICs operating over a 5.5 V–70 V supply range (6EDL7151) with a 1.5 A source/sink peak gate drive current. Both offer more than 50 programmable parameters over a built-in SPI interface, letting a designer configure the driver to a specific MOSFET rather than committing to a fixed drive strength at layout time.

Integrated motor control SiPs

The MOTIX™ IMD700A and IMD701A are motor control system-in-package (SiP) devices -- see the portfolio overview above for how SiP differs from SoC -- integrating the XMC™1404 microcontroller (Arm® Cortex®-M0 core) with the 6EDL7141 3-phase gate driver IC in one package, over a 5.5 V–60 V operating range. Field-Oriented Control (FOC) -- a motor control technique that regulates torque- and flux-producing current independently for smooth, efficient operation -- can be implemented directly on the integrated XMC™1404 core, so the SiP does not require a separate control MCU.

What specs define the right brushless DC motor driver?

Selecting the right motor control solution starts with five key parameters: supply voltage, motor power, functional safety requirements, preferred integration level, and targets for PCB space and bill-of-materials cost.

For motors below 150 W, highly integrated system solutions such as SoCs or SiPs are often the most cost-effective choice. For motors rated between 150 W and 1 kW, motor drivers with integrated functions such as an LDO and a transceiver offer a suitable option alongside MCU-based SoC or SiP solutions. At higher power levels, particularly above 500 W when stringent safety requirements apply, a discrete gate driver can be the preferred approach.

Safety requirements also influence device selection. Highly integrated solutions can be well suited for applications with no functional safety requirements or requirements up to ASIL B, while ASIL C and above may favor a discrete motor gate driver.

And finally, the choice also depends on the integration preference: a single-chip solution can reduce PCB space and component count, while a discrete architecture offers more flexibility and power headroom.

  • MOTIX™ gate driver ICs — flexible solutions with functional safety support up to ASIL D
  • MOTIX™ motor system ICs —  compact, ISO 26262-ready solutions with a flexible choice of MCU
  • MOTIX™ motor control SoCs/SiPs — Arm® Cortex®-M-based solutions with ASIL B product variants
