Automotive motor drivers bring LIN-ready single chip solution to BLDC motors, actuators
The new IC family consists of 4 base members; the MLX81205, MLX81207, MLX81210 and MLX81215. Each is available with a variety of memory configurations and in different package options. They all follow the very successful MLX81200 core integration concept - combining a voltage regulator, LIN transceiver, microcontroller unit (MCU), EEPROM, Flash, RAM, power FET pre-driver and several dedicated circuit blocks for highly efficient BLDC motor control from a single chip. Customers can realize a very small PCB design with a minimal bill of materials (BOM) to create simple or sophisticated actuators.
The IC family is 45 V load dump protected and will be qualified according AEC-Q100 grade 0 for high temperature automotive application support. As with the MLX81200, the drivers utilize Melexis' patented TruSense sensor-less driving algorithms in hardware and software for starting and driving BLDC motors using different construction schemes in a reliable way under unknown load conditions. Different current wave form profiles (block, trapezoidal and sinusoidal) can be applied for energy efficient motor performance.
This family also employs an innovative solution for slope control on power transistor switching, allowing customers to optimize in software the EMC behavior, as well as thermal dissipation of the power transistors during the switching process.The slope control function addresses several problems of electronic and mechatronic designers who only have a very limited PCB space available to solve heat and EMC problems.
The new IC family concept allows platform designs, so that a high reuse in software and discrete hardware is achievable.
The first family member, the MLX81215 in a QFN48 7x7 package with software development setups, is available for alpha customers. Next family members and a general availability for developments at customers are planned to be ready in the next months.
