With the FU7512Q1, FU7564Q1, FU7565Q1 and FU7574Q1, Fortior offers a family of microcontrollers specifically designed for automotive motor control applications. All devices are qualified to AEC-Q100 Grade 1 and support an operating temperature range from −40 °C to +125 °C. Together they provide scalable solutions ranging from single low-voltage motors to dual-motor systems and high-performance heat pump compressors.
Unlike general-purpose microcontrollers, the FU75xxQ1 family has been developed from the ground up for motor control.
Many functions that normally require additional software or external components are already implemented in dedicated hardware.
Depending on the device, the MCUs integrate features such as:
This high level of integration reduces component count, simplifies hardware design and shortens development time while improving EMC performance.
The devices support both sensorless and sensored BLDC and PMSM motors, as well as induction and servo motors, allowing designers to use a common hardware platform across multiple automotive applications.
At the heart of the FU75xxQ1 family is Fortior’s dedicated motor control architecture featuring hardware-assisted Field-Oriented Control (FOC).
The control platform incorporates advanced technologies including:
These technologies enable:
For electric auxiliary drives, this translates into quieter operation and lower energy consumption.
Reliability is a key requirement in automotive electronics.
The FU75xxQ1 family therefore incorporates extensive hardware protection functions, including:
Since these functions are implemented entirely in hardware, protection reactions occur within microseconds without software intervention. In the event of a fault, the power stage can be shut down immediately, significantly improving overall system safety.
Rather than offering numerous similar devices, Fortior has optimized the FU75xxQ1 family for four clearly defined application areas.
The FU7512Q1 targets high-performance applications using external gate drivers.
Dual independent PWM modules enable the control of two three-phase motors, while BiSS interfaces, extensive analog peripherals and hardware support for interleaved PFC make the device particularly suitable for:
The FU7564Q1 integrates gate drivers, power management and communication interfaces into a single device, significantly reducing external circuitry.
Typical applications include:
Designed specifically for modern 48 V vehicle architectures, the FU7565Q1 integrates a high-efficiency buck converter while providing excellent EMC robustness.
Typical applications include:
The FU7574Q1 integrates two independent gate drivers, allowing two three-phase motors to be controlled simultaneously from a single MCU.
Independent monitoring of both channels ensures that a fault in one motor does not affect operation of the other.
Typical applications include:
| P/N | MCU | Motors (max.) | Driver-Output | Gatedriver |
| FU7512Q1 | RISC-V | 2 | 2* PWM | # |
| FU7564Q1 | RISC-V | 2 | 1* PWM | 1* 6N 40V |
| FU7565Q1 | RISC-V | 1 | # | 1* 6N 80V |
| FU7574Q1 | RISC-V | 2 | # | 2* 6N 40V |
The FU75xxQ1 family provides a highly integrated motor control platform for modern automotive electronics.
By combining dedicated motor control hardware, advanced FOC algorithms, integrated gate drivers and comprehensive protection functions, these MCUs enable compact, robust and cost-effective solutions for a wide range of automotive applications—from single low-voltage auxiliary motors to sophisticated dual-motor systems and high-performance heat pump compressors.
