I. Motor SBC (System-on-Chip): Integrated BDC Motor Control Platform
The Infineon MOTIX™ Motor SBC is an integrated system-on-chip (SBC) designed specifically for BDC/BLDC low-voltage motor applications. It is also the industry’s first single-chip solution to deeply integrate motor control functions, power management, in-vehicle bus communication and gate driver units. This completely overcomes the architectural challenges of traditional motor control systems—characterised by ‘multiple discrete chips and complex peripheral circuits’—and serves as the core platform for standardised control of small-to-medium-power BDC motors.

1. Core Integrated Architecture
The motor SBC utilises a compact 7×7 mm package and incorporates a complete set of core motor control hardware modules internally, eliminating the need for additional power management, communication and basic driver chips, thereby significantly simplifying the PCB layout. The core integrated units include: a high-precision, low-dropout regulator (supporting a regulated output of 250 mA at 5 V); standardised LIN/CAN FD bus communication interfaces; multi-channel half-bridge MOSFET driver units; signal acquisition and conditioning circuits; and a basic fault diagnosis module. These enable the motor SBC to independently handle power supply regulation, signal exchange, power drive and status monitoring for BDC motors.

2. Key Technical Advantages
Firstly, it incorporates Infineon’s patented adaptive MOSFET gate drive technology, which dynamically adjusts the gate drive rate to precisely balance switching losses and electromagnetic interference. This effectively reduces EMI noise during the start-stop and speed regulation of BDC motors, fully meeting the stringent electromagnetic compatibility standards for automotive electronics. Secondly, its high level of integration significantly reduces system bill of materials costs and assembly complexity, minimises the number of peripheral components, and enhances the unit’s immunity to interference and operational stability. Thirdly, it is compatible with 12V automotive low-voltage systems and is specifically optimised for automotive auxiliary motor applications; with a wide operating temperature range, it can withstand voltage fluctuations and temperature variations inherent in complex in-vehicle operating conditions.

3. Core Application Scenarios
Primarily suited for the control of low-voltage auxiliary BDC motors in automotive applications, including window lift motors, sunroof drive motors, seat adjustment motors, air conditioning damper actuators, and in-vehicle water pump and fan motors—all of which are small-to-medium power devices. It is also suitable for industrial low-voltage drives and small motors in smart home applications, where cost, stability and integration are key requirements.

II. BDC Motor Gate Drivers: High-Power, Multi-Channel Expansion Drive Core
The Infineon MOTIX™ TLE9210x series comprises dedicated gate driver ICs tailored specifically for BDC (Brushless Direct Current) motors. Designed for high-power, multi-channel synchronous motor drive and highly reliable industrial and automotive applications, these ICs feature flexible power scaling capabilities and comprehensive safety protection. As the core drive components for multi-channel, high-power BDC motor control systems, they overcome the performance limitations of SBCs in high-power, multi-motor scenarios.

1. Key Product Features
This series of single-chip solutions can integrate up to eight half-bridge drive channels, capable of driving up to 16 N-channel MOSFETs. It supports synchronous control of multiple BDC motors or multi-winding motors, with flexible channel configuration allowing the H-bridge drive architecture to be configured as required to accommodate all BDC motor control logic scenarios, including forward and reverse operation, speed regulation and braking. It also supports motor cascade expansion, allowing multiple chips to work in concert to further increase the number of drive channels, thereby meeting the control requirements of multi-motor clusters.
Taking the flagship model TLE92108-232QX as an example, it features adaptive multi-level MOSFET gate control technology, which optimises drive timing for MOSFETs of different power ratings, thereby reducing switching losses and heat generation whilst enhancing the drive efficiency of high-power BDC motors. The device fully complies with RoHS environmental standards and has passed automotive-grade reliability certification, making it suitable for demanding industrial and automotive applications.

2. Safety and Diagnostic Capabilities
The chip incorporates a comprehensive suite of intelligent protection and diagnostic functions, covering fault detection such as overvoltage, undervoltage, overcurrent, overheating, MOSFET short-circuit and motor stalling. It monitors the motor’s operating status in real time and rapidly shuts down the drive channels in the event of a fault, thereby preventing the burnout of power devices and damage to the motor. It also supports fault code reporting, facilitating system debugging and equipment maintenance, whilst significantly enhancing the control system’s safety and fault tolerance.

3. Application Scenarios
Primarily designed for medium- to high-power BDC motors and multi-motor synchronous control scenarios, including automotive chassis auxiliary motors, small industrial drive motors, equipment lifting actuators and high-power automotive pump units. It is suitable for high-end industrial and automotive applications with stringent requirements regarding drive power, number of channels and operational safety.

III. BDC Motor Control SoC: Single-Chip, Full-Featured Intelligent Control Solution
Infineon’s MOTIX™ motor control SoC (System-on-Chip) is a high-end, integrated intelligent solution for BDC motor control. Unlike the basic integrated architecture of SBCs and the purely drive-oriented nature of gate drivers, the SoC fully integrates a high-performance MCU core, memory units, analogue peripherals, communication interfaces, power drive stages and power management modules onto a single chip, achieving a fully integrated ‘computation + control + drive + communication’ solution. eliminating the need for an external master control chip and making it the optimal choice for intelligent, high-precision BDC motor control.

1. Core Hardware Architecture
The BDC motor control SoC is equipped with a high-performance Arm Cortex-M series core, features built-in high-speed flash memory and SRAM storage units, and integrates a high-precision 14-bit Σ-Δ ADC (analogue-to-digital converter) capable of accurately acquiring operating parameters such as motor current, voltage and speed. It also integrates CAN and LIN bus transceivers, multiple H-bridge/half-bridge driver units and a regulated power supply module. Certain models support the ISO 26262 functional safety standard and feature a built-in safety switch circuit to meet in-vehicle functional safety requirements.
Represented by the TLE9891-2QTW61, these core models enable a single chip to independently perform complex algorithms such as closed-loop speed control, precise forward and reverse control, stall protection and adaptive parameter adjustment for BDC motors, completely eliminating the need for an external MCU and streamlining the system architecture to the greatest extent possible.
