All-in-one controller family to offer flexibility in driving small motors

November 04, 2014 // By Christoph Hammerschmidt
With its new family of microcontrollers Micronas drives integration further, enabling very compact servo motor solutions for automotive and industrial application environments.

All devices of the new family are designed to connect directly to the motor windings without the need for external MOSFETs; they also can be supplied directly by the 12 V car batteries without need for external voltage regulators. The integrated LIN transceiver allows the direct connection to the LIN bus. All family members are powered by an ARM Cortex-M3 core offering high processing efficiency and low interrupt latency, enabling the implementation of complex commutation schemes to optimize the size-torque ratio of the electric motor.

The new product family also provides a unique level of flexibility in driving small motors. Implemented in mixed-signal HV CMOS technology, the devices can be programmed to drive BDC, BLDC, or stepper motors. This versatility enables customers to significantly reduce their cost of ownership, as a single device can be used for several different motor control applications, especially preserving the software invest when moving from BDC or stepper to BLDC motor design. The use of an industry standard core and a state-of-the-art development tool-chain combined with Micronas' demonstration software and application notes guarantees an efficient implementation of the customers’ production software – gaining fast time to market.

The new controller family is particularly suited to address the need for intelligent actuators in automotive applications such as HVAC flaps, active grille shutters, pumps, air cooling fans (such as LED cooling fans) or mechanical actuators in cornering lights.

First family members will be announced in the first half of 2015. Micronas will provide further information on the new controller family at Electronica (hall A6, booth 213).
