EVAL-L99ASC03 L99ASC03 Evaluation Board Data brief Description The EVAL-L99ASC03 is an evaluation board designed for sensorless 3Phase BLDC motor control. It s composed by a mother-board and a daughter-board on which is pre-assembled the L99ASC03. The system features an enhanced power management power supply functionalities including various standby modes. The motherboard, based on STM8 Features microcontroller, provides the logic section for monitoring and driving the L99ASC03 assembled Two separated and signal shielded stages: in the daughterboard. driver & power With the aim to make the board usage and ISO pulse protection (not soldered) settings simpler, ST provides a dedicated user- Reverse polarity protection available on each friendly software with a Graphic User Interface battery voltage input: Vs, VSREG, power stage (GUI). This enables the user to set L99ASC03 Current reference comparator parameters and at the same time it shows real time device information as the current evolution, PCB temperature sensor motor speed (RPM), the fault flags, the board Hall sensors connector and conditioning circuit temperature and much more.
