STMicroelectronics has launched the EVAL-L99ASC03 designed for sensorless three-phase brushless DC (BLDC) motor control. The board is composed of a mother and a daughterboard with a L99ASC03 motor pre-driver IC. The system features enhanced power management functionalities including various standby modes. The motherboard is based on the STM8 microcontroller unit (MCU). It provides the logic section for monitoring and driving the IC.
Also included is software with a graphic user interface (GUI). This enables engineers to set parameters and also displays real time device information.
