Melexis extends its smart embedded motor drive portfolio

Melexis has extended 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 100W to 1000W.

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 pre-driving a range of high-power BLDC motors.

With the ability to drive 12V motors in either a sensor or sensorless configuration the MLX81206 is intended for silent and high-performance hvac blowers, engine cooling fans and pumps in conventional, hybrid and full electric vehicles.

Melexis has been able to achieve a high level of integration, bringing together an embedded driver with high-voltage analogue circuitry and digital technology, including Flash and non-volatile RAM memory along with an embedded microcontroller, making the MLX81206 a highly efficient and complete single-chip solution combining both hardware and software.

The device has been designed to interface to a range of sensors, such as the MLX90380 resolver for dynamic pumps driven in Field-Oriented-Control mode (FOC).

This IC can be delivered in a small footprint QFN32 package (MLX81206) or in a leaded package TQFP48 (MLX81208).
