MOTIX™ MCU | 32-bit motor control with integrated relay driver
LIN based MOTIX ™ 32-bit motor control SoC portfolio based on Arm® Cortex®- M0 provides scalable motor control solutions
The MOTIX™ TLE984x 32-bit motor control SoC solution, featuring the Arm® Cortex®-M0 core with an integrated relay driver, combines a microcontroller and a LIN transceiver on a single die. This allows it to sense, control, and actuate motors via a relay. It’s specifically designed for a wide range of LIN-slave motor control applications, such as window lifts and sunroofs, and is supported by a comprehensive development tool chain.
- Arm® Cortex®-M0 core
- Up to 40 MHz frequency
- Up to 64 kB flash
- Relay driver IC
- Integrated LIN transceiver
- Temperature range Tj up to 150°C
System-on-chip (SoC) with Arm® Cortex®-M0 and relay driver
The MOTIX™ TLE984x product family brings together the Arm® Cortex®-M0 core and the market proven peripherals. It integrates on a single die all the necessary functions to sense, control and actuate a motor via a relay. Produced on Infineon’s first-in-industry automotive qualified 130 nm smart power technology, the Infineon MOTIX™ TLE984x mixed-signal MCU offers an unmatched level of integration as well as system cost to performance optimization for the target application segments.
MOTIX™ TLE984x offers scalability in terms of flash memory sizes ranging from 36 kB to 64 kB with pin-compatible devices and with up to two high-side switches. It is specifically designed to fit to a wide range of LIN-slave motor control applications such as window lifts,and sunroofs.
The MOTIX™ TLE984x family is supported by a complete development tool chain provided by Infineon and third-party vendors. The tool chain includes compiler, debugger, evaluation board, LIN low level driver and configuration tool as well as various software code examples.
Highlights and benefits of MOTIX™ 32-bit motor control SOC with integrated relay driver
- Enable cost and board space improvements – Our system-on-chip solution integrates data processing, actuation and sensing. The chip comes in a leadless VQFN package with 7 x 7 mm footprint and enables PCB space saving. The MOTIX™ TLE984x family allows driving relays and MOSFETS at VBATT ≥ 6 V without external components, providing a very cost-effective solution on a system level.
- 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, both the Embedded Power IC and the external MOFESTS can be protected.
- Support multiple and flexible designs with minimal effort – All MOTIX™ TLE984x devices are pin and software compatible, maximizing a single design through scalability
MOTIX™ MCU tool chain and design-in support
