  • The L99DZ200 is a 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 5 high-side drivers to supply LEDs, 2 high-side drivers to supply bulbs increase the system integration level. Three High Side drivers can be configured to support the so-called Constant Current mode conceived to supply external LED modules with huge decoupling capacitors
    Up to 3 DC motors and 8 external MOS transistors (4 for each of the 2 H-bridges) 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.
