Systems-on-chip (SoC) for pumps and fans in thermal-management motor control introduced by Infineon

Summary points:

• The TLE994x and TLE995x are designed for brushed and brushless motor control in small- to medium-sized automotive applications.
• Each device combines a gate driver, microcontroller, communication interface, and power supply, supporting ISO 26262 (ASIL B) functional safety.
• Featuring an Arm Cortex-M23 core that runs as fast as 40 MHz, advanced diagnostics, and protection features for dependable performance in electric vehicles and comfort systems.

MUNICH – Infineon Technologies AG in Munich is introducing the TLE994x and TLE995x members of the company's MOTIX 32-bit motor control systems-on-chip (SoC) for brushed (BDC) and brushless (BLDC) motor applications.

These products are tailored for small- to medium-sized automotive motors, ranging from functions such as battery cooling in electric vehicles to comfort features such as seat adjustment.

Based on Infineon's experience in motor control, the SoCs combine advanced integration with functional safety and cyber security features.

The three-phase TLE995x (BLDC) is for pumps and fans in thermal-management systems, while the two-phase TLE994x (BDC) targets comfort functions such as electric seats and power windows. Both devices integrate advanced diagnostic and protection functions that support reliable motor operation.

Arm Cortex-M23 core

The SoCs combine a gate driver, microcontroller, communication interface, and power supply in one chip. The LIN-based devices feature an Arm Cortex-M23 core running as fast as 40 MHz, with integrated flash and RAM.

The TLE994x/5x offers enhanced peripherals, flexible PWM generation via the CCU7, and automatic LIN message handling to reduce CPU load. All devices comply with ISO 26262 (ASIL B) for functional safety.

Infineon also provides evaluation boards, configuration and simulation tools, and dedicated software packages. A 150-Watt water pump reference design and FOC motor control software support rapid prototyping.
