Benefits and highlights of MOTIX™ MCU (SoC) with integrated 3-phase bridge driver
- Enable cost and board space improvements – Our solution for BLDC motor control integrates data processing, actuation and sensing. The chip comes in a small package which enables PCB space saving. It allows driving MOSFETs at VBATT ≥ 6 V with a low number of external components, providing reduced BOM cost on a system level.
- Support in-cabin and underhood applications with same design – Some MOTIX™ TLE987x and TLE989x 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. In addition, MOTIX™ MCU (SoC) and the external MOFESTs can be protected.
- Enable high performance – The MOTIX™ TLE989x family, part of this product portfolio, comes with CAN/CAN-FD communication interface and addresses high power 3-phase motor driver applications with secure motor control approach.
- Enable safety – Some of the MOTIX™ TLE989x variants have ASIL B rated safety level. They enable fail safe mechanism and error handling with safe switch off path for bridge driver

What is the adaptive MOSFET gate control feature?
Many MOTIX™ motor control ICs use a patented concept of adaptive MOSFET gate drive. This multi-stage slew rate control enables EMC tuning via SPI, including adjusting slew rate with independence from dead-time and turn on/off delays. The on-board measurement and self-adaption of external MOSFET switching times allows balancing of power dissipation vs. EMC performance, adjusts for MOSFET lot-to-lot variations and reduces the need of end-of-end line calibration effort.
Adaptive MOSFET control is an integrated feature of MOTIX™ TLE985x and TLE988x families with integrated h-bridge driver and of MOTIX™ TLE989x family with integrated 3-phase bridge driver.
