Infineon adds to Motix family with automotive ICs with CAN FD
Infineon Technologies has introduced the TLE988x and TLE989x devices to its Motix microcontroller embedded power IC portfolio. The SoCs integrate a gate driver, microcontroller, communication interface and power supply on a single chip to achieve a minimal footprint, said Infineon.
The Motix MCU TLE988x two-phase bridge driver family and the Motix MCU TLE989x three-phase bridge driver family include multiple devices which offer flash sizes of up to 256kbyte and support temperature ranges (T j max) up to 175 degrees C.
The TLE988x and TLE989x families feature CAN (FD) as the communication interface. The ICs are AEC Q-100 -qualified and are therefore suitable for automotive brushed DC and brushless DC motor control applications in vehicle body, comfort, and thermal management applications.
The new microcontrollers address customers’ needs for small, integrated, smart motor control devices, with fast and very robust on-chip CAN FD transceivers for host communication, commented Andreas Doll, senior vice president and general manager, smart power at Infineon. They offer approximately 60 per cent more processing power compared to the existing TLE987x product family, he added. They also provide functional safety and cybersecurity functions which are becoming increasingly important for oil pumps in thermal management systems in electric vehicles, he said.
The TLE988x and TLE989x use a B4 or B6 bridge N-channel MOSFET driver, respectively, an Arm Cortex M3 microcontroller, and a CAN (FD) controller and transceiver supporting a communication speed of 2Mbits per second. In addition to fast and robust communication, they are also claimed to deliver the highest computing performance due to the high system frequency (60MHz) and dual flash enabling read-while-write operation.
The microcontrollers are also ISO 26262 (ASIL B) -compliant and Infineon offers some variants with built-in cybersecurity.
The SoCs are offered in a 7.0 x 7.0mm TQFP package.
In addition, the ICs feature Infineon’s patented Adaptive MOSFET Control algorithm, which compensates for the variation of MOSFET parameters by automatically adjusting the gate current to achieve the required switching. This allows the system to be optimised for EMI (electromagnetic emissions, slow slew rates) and power dissipation (short dead times). Adaptive MOSFET Control also enables supply chain flexibility by maintaining the same switching behaviour across variations in MOSFET production lots or differences between MOSFET suppliers.
To accelerate the evaluation and design-in process, the Motix MCU embedded power ICs are supported by a comprehensive ecosystem that includes software, evaluation boards and kits as well as simulation, configuration and visualisation tools.
The Motix MCU TLE988x and TLE989x devices are in production and available now. Two variants in LQFP package with 64 pins will follow in December 2023.
