Embedded Motor Controllers for Smart Actuators
Introduction
The Micronas high-voltage controller family combines an Arm standard microcontroller core with a wide range of additional functions which, up to now, could only be realized via discrete circuit elements.
The family is designed as an embedded controller for smart actuators. It features advanced integration for compact and cost-effective system designs for use in automotive applications and beyond (industrial, consumer, instrumentation, etc.).
Replacement of conventional mechanical drive by “on-demand” electric drive and a general adoption of more efficient electrical motors are the main reasons for a growing demand for cost-effective system solutions for electrical motor control and drive. Long lifetime reliability, reduction of weight and overall dimension are additional key issues which have to be addressed especially for automotive applications. Thanks to their better efficiency, lower acoustic- and electrical noise, brushless DC (BLDC) are gaining a significant share of the electrical motors by replacing brushed (BDC) motors.
Micronas´ High-Voltage Controllers integrate almost all surrounding circuits needed for driving electrical motors. In addition to the UART interface, the built-in networking capabilities enable the deployment of LIN bus control compliant to LIN-2.x for a wider range of applications like e.g. remote smart actuator. Reducing the number of external components to a minimum, the product’s flexible peripherals allow direct controlling of brushless, brushtype DC- and Stepper electrical Motors, by means of three fully integrated half-bridges. Thanks to this flexibility in driving the electrical motor, the HVC controllers provide an effective system solution for both small and medium sized electrical motors, enabling a common product platform. This gives our customers a decisive competitive edge because they are much faster at the implementation stage and need fewer resources in the development process of their various applications.
