The MLX81346 is a gen-3 LIN pre-driver for 12 V, 24 V and 48 V DC & BLDC motors targeting automotive mechatronic applications up to 1000 W (12 V) or up to 2000 W (48 V). It benefits from an extended memory of 90 KB. Top features LIN Motor driver Microcontroller Memories split per CPU Product description The MLX81346 is a gen-3 LIN pre-driver for 12 V, 24 V and 48 V motors targeting automotive mechatronic applications up to 1000 W (12 V) or up to 2000 W (48 V). It benefits from an extended memory of 90 KB. This all-in-one LIN pre-driver enables small-footprint applications to control DC and BLDC motors, and support sensored or sensorless field-oriented control (FOC) algorithms. The MLX81346 pre-driver addresses multiple mechatronic applications: 12V-48V DC/BLDC Engine Cooling Fans, Pumps, Compressors 12V-48V DC/BLDC Positioning Actuators, including Robotics 36V-48V BLDC e-bikes, e-scooters For engineering development, the MLX universal master (MUM) can be used to program and interface the IC. For production, third-party equipment & SW must be used.
