Infineon Applied sciences is increasing its MOTIX 32-bit motor management SoC (System-on-chip) household with new options for each brushed (BDC) and brushless (BLDC) motor functions: TLE994x and TLE995x. The brand new merchandise are tailor-made for small- to medium-sized automotive motors, starting from capabilities similar to battery cooling in electrical autos to consolation options similar to seat adjustment. The variety of such motors continues to develop in fashionable, particularly electrical, autos and they’re utilized in an growing variety of safety-critical functions.
Due to this fact, automotive producers require dependable, compact and cost-effective options that
combine a number of capabilities. Based mostly on Infineon’s in depth expertise in motor management, the
new SoCs mix superior integration with practical security and cybersecurity-relevant
options.
The three-phase TLE995x (BLDC) is right for pumps and followers in thermal administration
programs, whereas the two-phase TLE994x (BDC) targets consolation capabilities similar to electrical
seats and energy home windows. Each units combine superior diagnostic and safety
capabilities that assist dependable motor operation.
By combining a gate driver, microcontroller, communication interface, and energy provide in a single chip, Infineon’s SoCs provide distinctive performance with minimal footprint. The brand new LIN-based units characteristic an Arm Cortex-M23 core working as much as 40 MHz, with
built-in flash and RAM. Area-Oriented Management (FOC) functionality ensures environment friendly and
exact motor operation. In comparison with the established TLE986x/7x household, the TLE994x/5x
presents enhanced peripherals, versatile PWM era by way of the CCU7, and automated LIN
message dealing with to scale back CPU load. All units adjust to ISO 26262 (ASIL B) for
practical security. Moreover, the built-in Arm TrustZone know-how gives a
basis for improved system safety.
