System-on-chip (SoC) with Arm® Cortex®-M3 or M0 and h-bridge driver
Infineon’s MOTIX™ MCU 32-bit motor control SoC portfolio with integrated H-bridge driver comprises four product families: TLE985x, TLE986x, TLE988x, and TLE994x.
These products integrate market-proven peripherals with either LIN or CAN/CAN-FD communication, addressing a wide range of smart 2-phase DC motor control applications such as sunroofs and window lifts.
The TLE985x family is built around a 32-bit Arm® Cortex®-M0 core. Meanwhile, the TLE986x and TLE988x families are powered by the more advanced Arm® Cortex®-M3 core, while the TLE994x family features the Arm® Cortex®-M23 core.
Notably, the TLE986x shares the same microcontroller unit and peripherals as the MOTIX™ TLE987x family, which integrates a 3-phase bridge driver. This commonality facilitates design synergies between DC and BLDC motor control applications.
Moreover, the same design advantage extends to the TLE988x and TLE989x families, as well as the TLE994x and TLE995x families.
Benefits and highlights of MOTIX™ MCU (SoC) with integrated h-bridge drivers
- Enable cost and board space improvements: Our system-on-chip solution for DC motor control integrates data processing, actuation and sensing. The chip comes in a small package and enables PCB space saving. MOTIX™ MCU (SoC) with integrated h-bridge driver can driver MOSFETs at VBATT ≥ 6 V with a low number of external components, providing a very cost-effective solution on a system level.
- Support in-cabin and underhood applications with same design: Some derivatives are qualified up to Tj = 175°C and therefore enable a family design approach due to pin, package and software-compatibility.
- Enable high levels of system reliability: Extensive diagnostics and protections are embedded within the system-on-chip, more than a discrete approach can offer.
- Enable high performance: The MOTIX™ TLE988x family, part of this product portfolio, comes with CAN/CAN-FD communication interface and addresses high power BDC applications with secure motor control approach.
- Enable safety: Some of the MOTIX™ TLE988x and all TLE994x variants have ASIL B rated safety level. They enable fail safe mechanism and error handling with safe switch off path for bridge driver.
