About

What are the features of MOTIX™ motor control SoCs with relay driver?

The MOTIX™ TLE984x motor control SoC is based on the Arm® Cortex®-M0 microcontroller and integrates the relay driver, power supply and LIN communication interface on a single die.

Produced on Infineon’s first-in-industry automotive qualified 130 nm smart power technology, MOTIX™ TLE984x is designed to fit to a wide range of LIN-slave motor control applications such as window lifts and sunroofs. The mixed-signal MCU offers an unmatched level of integration as well as system cost to performance optimization for the target application segments.

Highlights:

Cost and board space improvements

  • VQFN package with 7 x 7 mm footprint
    • Allows driving relays and MOSFETS at VBATT ≥ 6 V without external components
  • High levels of system reliability
    • Extensive diagnostics and protections are embedded to protect the MOTIX™ MCU SoC and the external MOSFET
  • Scalability to support multiple designs
    • Pin and software compatible product family
    • With flash memory sizes ranging from 36 kB to 64 kB

What are the features of MOTIX™ motor control SoCs with half-bridge driver?
  • The MOTIX™ TLE985x motor control SoCs with integrated half-bridge driver feature a 32-bit Arm® Cortex®-M0 microcontroller, a voltage regulator and a communication interface. This single-phase solution utilizes either Pulse Width Modulation (PWM) or LIN for automotive brushed DC (BDC) motor control applications.

Highlights:

  • Cost and board space improvements
    • VQFN package with 7 x 7 mm footprint
    • Allows driving relays and MOSFETS at VBATT ≥ 6 V without external components
  • High levels of system reliability
    • Extensive diagnostics and protections are embedded to protect the MOTIX™ MCU SoC and the external MOSFET
  • Adaptive MOSFET control
    • On-board measurement and self-adaption of external MOSFET switching times allow balancing of power dissipation vs. EMC performance, adjust for MOSFET lot-to-lot variations and reduce the need for end-of-line calibration effort.
