  • The L99ASC03G is a multifunctional system IC designed for three-phase motor control applications.

    The device features a voltage regulator to supply an external microcontroller and an operation amplifier for motor current sensing. It is designed to control six external N-channel MOSFETs in bridge configuration to drive three-phase motors in automotive applications. All gate driver outputs are controlled by separate inputs.
    The integrated Serial Peripheral Interface (SPI) makes it possible to adjust device parameters, control all operating modes and read out diagnostic information.

    主要特性

    • AEC-Q100 qualified
    • 5 V low-drop voltage regulator (200 mA continuous mode)
    • Very low current consumption in standby mode (typ. 15 μA)
    • ST SPI interface for control and diagnostics
    • Window watchdog and fail-safe functionality
    • Two separate power supply pins
    • Three half-bridge drivers to control external MOSFETs (configurable by SPI)
    • Full drive of external MOSFETs down to 6 V input voltage
    • Input pin for each gate driver (with cross-current protection)
    • Two-stage charge pump supporting 100% duty cycle
    • PWM operation up to 80 kHz (not restricted)
    • Current-sense amplifier (configurable by SPI)
    • Disable input to turn off gate driver outputs
    • Analog multiplexer output to monitor external power supply voltages and internal junction temperature
    • Advanced BEMF detection IP
    • Overcurrent protection (programmable)
    • Drain-source monitoring and open-load detection
    • TQFP48 7 x 7 x 1 mm with Exposed Pad (4.5 x 4.5 mm) package

    • Based on the EVAL-L99ASC03 evaluation board designed for sensorless 3-phase BLDC motor control, the system features enhanced power management power supply functions including various standby modes. The motherboard, based on an STM8 microcontroller, provides the logic section for monitoring and driving the L99ASC03G 3-phase motor pre-driver assembled in the daughterboard. 

      ST also provides dedicated user-friendly software with a Graphic User Interface (GUI) that enables the user to set L99ASC03G parameters while displaying device information in real time.

      Developers can easily evaluate their brushless DC motor control solution for a variety of circulation and booster pump applications for coolant, water, fuel or oil lines.
