Product Description
- The L99ASC03 is a Multifunctional System IC 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.
- Very low current consumption in standby mode (typical 15µA)
- ST SPI interface for control and diagnostics
- Window watchdog and failsafe functionality
- Two separate power supply pins
- Three half-bridge drivers to control external MOSFETs (configurable by SPI)
- Full drive of external MOSFETs down to 6V input voltage
- Input pin for each gate driver (with crosscurrent protection)
- Two-stage charge pump supporting 100% duty cycle
- PWM operation up to 80kHz (not restricted)
- Current-sense amplifier (configurable by SPI)
- Disable input to turn-OFF gate driver outputs
- Analogue multiplexer output to monitor external power supply voltage & internal junction temperature
- Advanced BEMF detection IP
- Overcurrent protection (programmable)
- Drain-source monitoring and open-load detection
- 5V Low-drop voltage regulator (200mA continuous mode)
