Melexis extends its smart embedded motor drive portfolio for automotive applications
Latest generation II motor predriver offers more Flash memory, LIN interface and easy sensor integration.
Tessenderlo, Belgium, 29 April 2019 - Melexis announces the latest addition to its generation II embedded motor driver product portfolio for automotive applications, with the release of the MLX81206. This single-chip solution with 64 KB Flash memory offers higher integration with the ability to drive BLDC motors from 100 W to 1,000 W.
The MLX81206 supports a LIN 1.x/LIN 2.x and SAE J602 compliant interface, the most widely used digital communications interface standards in the automotive sector, making it a simple solution to predriving a range of high-power BLDC motors. With the ability to drive 12 V motors in either a sensor or sensorless configuration the MLX81206 is the ideal choice for silent and high-performance HVAC blowers, engine cooling fans and pumps in conventional, hybrid and full electric vehicles.
Melexis engineers have achieved a high level of integration, bringing together an embedded driver with high-voltage analog circuitry and digital technology, including Flash and non-volatile RAM memory along with an embedded microcontroller. This makes the MLX81206 a highly efficient and complete single-chip solution combining both hardware and software.
The synergy between sensing and drive control makes the MLX81206 a compelling choice in terms of size, performance and robustness. This is apparent by the ease with which the device can interface to a range of sensors, such as the MLX90380 resolver for dynamic pumps driven in Field-Oriented-Control (FOC) mode. This IC can be delivered in a small footprint QFN32 package (MLX81206) or in a leaded package TQFP48 (MLX81208).
