The MLX81334 LLW-AMT-001-RE from Melexis is an Automotive Qualified Smart LIN Motor Driver IC that has been designed for various types of motors, including DC, BLDC, and stepper motors. It requires an input voltage of up to 28 V. This motor driver features a low on-resistance for 1 half-bridge + shunt configuration, ensuring efficient motor control operation. It is equipped with dual N-channel field effect transistors (FETs) for each half-bridge and an on-chip charge pump for top-FETs, thereby resulting in a reliable performance. This motor driver is powered by the MLX16-FX application CPU and the MLX4 communication CPU for efficient processing capabilities. It integrates 2 watch-dog timers, a +50 input interrupt controller, a common-purpose timer, and split memories for each CPU.
This AEC-Q100-qualified motor driver incorporates advanced safety features such as a temperature sensor, over-temperature detection, over-current detection, over-voltage protection, and under-voltage protection, ensuring effective temperature monitoring and comprehensive safeguards against electrical faults and potential system damage. It is available in a surface-mount package that measures 5 x 5 mm and is ideal for small stepper/BLDC flaps or valves, as well as small DC flaps or valves, or single-coil fan applications.
