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.

The L99DZ100G and L99DZ100GP are door zone systems IC providing electronic control modules with enhanced power management power supply functionality, including various standby modes, as well as LIN and HS CAN physical communication layers. The two low-drop voltage regulators of the devices supply the system microcontroller and external peripheral loads such as sensors and provide enhanced system standby functionality with programmable local and remote wake-up capability. In addition 8 high-side drivers to supply LEDs, 2 high-side drivers to supply bulbs increase the system integration level. Up to 5 DC motors and 4 external MOS transistors in H-bridge configuration can be driven. An additional gate drive can control an external MOSFET in high-side configuration to supply a resistive load connected to GND (e.g. mirror heater). An electro-chromic mirror glass can be controlled using the integrated SPI-driven module in conjunction with an external MOS transistor. All outputs are SC protected and implement an open-load diagnosis. The ST standard SPI interface (4.0) allows control and diagnosis of the device and enables generic software development.

The L99DZ300G is a door zone system IC providing electronic control modules with enhanced power management power supply functionality, including various standby modes, as well as LIN and CAN FD physical communication layers. The device has two low drop voltage regulators to supply the system microcontroller and external peripheral loads such as sensors and provides enhanced system standby functionality with programmable local and remote wake-up capability. Moreover, the 10 high-side drivers (9 to supply LEDs and 1 to supply bulbs) increase the system integration level; all the high-side drivers support the constant current mode for LED module with high input capacitance. Up to 5 DC motors and 4 external MOS transistors in H-bridge configuration can be driven in PWM mode up to 25 kHz. An additional gate drive can control an external MOSFET in high-side configuration to supply a resistive load connected to GND (for example mirror heater). An electrochromic mirror glass can be controlled using the integrated SPI-driven module in conjunction with an external MOS transistor. All the outputs are SC protected and implement an open-load diagnosis. The ST standard SPI interface (4.0) allows control and diagnosis of the device and enables generic software development.
