Embedded controller for smart actuators

Introduction

The high-voltage microcontroller HVC 24xyB combines a standard microcontroller core with a wide range of additional functions which, up to now, could only be realized via external circuit elements.
The Micronas HVC 2480B, a high-voltage controller for use in automotive and in-dustrial applications, features advanced integration for a compact and cost-effective system design.
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 addi-tional key issues which have to be addressed especially for automotive applications like e .g. HVAC flaps. 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) and stepper motors.
Micronas ́ high-voltage controllers integrate almost all surrounding circuits needed for driving electrical motors. The built-in networking capabilities enable the deployment of LIN bus control 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 brushed and brushless electrical motors either by means of three fully integrated half-bridges or by controlling three external MOSFET half-bridges. Thanks to this flexibility in driving the electrical motor, HVC 24xyB 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.
