System-on-chip (SoC) with Arm® Cortex®-M0 and half-bridge driver
Infineon's single-phase solution, the MOTIX™ TLE985x 32-bit motor control SoC, offers the smallest footprint in its class. Built on the 32-bit Arm® Cortex®-M0 core, the MOTIX™ TLE985x integrates a gate driver, microcontroller, communication interface, and power supply on a single chip. It is specifically designed for smart DC brushed motor control applications, such as HVAC blowers.
This system solution enhances efficiency through smart power-on-demand control and provides a true mechatronic solution by placing the electronics directly at the motor. As a result, the external control signal (LIN or simple PWM) to the motor control minimizes emissions, preventing any interference with other electronic components in the vehicle.
Highlights and benefits of MOTIX™ MCU (SoC) with integrated half-bridge 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™ TLE985x 32-bit motor control SoC with integrated half-bridge driver allows driving MOSFETs at VBATT ≥ 6 V with a low number of external components, providing a very cost-effective solution on a system level. It helps to reduce BOM cost.
MOSFET driver with adaptive control: The MOTIX™ TLE985x family has an adaptive control hardware implementation. This algorithm is able to compensate MOSFET parameter spread in the system by automatically adjusting gate current values as a reaction on timing measurement results. This allows an optimization of the system concerning EME (slow slew rates) and Pdiss (short dead times) simultaneously.
Enable high levels of system reliability: Extensive diagnostics and protections are embedded within the system-on-chip, more than a discrete approach can offer.
