STMicroelectronics Evaluation Board The STMicroelectronics evaluation board is designed for sensorless 3Phase BLDC motor control and composed by a motherboard and a daughterboard with pre-assembled L99ASC03 IC. This system enhanced power management power supply functionalities including various standby modes. It is based on STM8 microcontroller, provides the logic section for monitoring and driving the IC. Features and Benefits: • Compatible with external power boards
• Current reference comparator
• Flash mode configurable
• Hall sensors connector and conditioning circuit
• INH_wake up button
• Microcontroller configured to be supplied by L99ASC03 5V LDO
• PCB temperature sensor
• Pulse protection (not soldered)
• Reverse polarity protection available on each battery voltage input: Vs, VSREG, power stage
• Two separated and signal shielded stages: driver and power
