Sales Briefcase
  • The L99DZ120 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 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 3 DC motors and 4 external MOS transistors in H-bridge configuration can be driven. 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.

    Key Features

    • Internal 10bit PWM timer for each stand-alone high-side driver
    • Buffered supply for voltage regulators and 2 high-side drivers (OUT15 & OUT_HS / both P-channel) to supply e.g. external contacts
    • Programmable soft-start function to drive loads with higher inrush currents as current limitation value (for OUT1-6, OUT7, OUT8 and OUT_HS) with thermal expiration feature
    • All the embedded outputs come with protection and supervision features:
      • Current Monitor (high-side only)
      • Open-load
      • Overcurrent
      • Thermal warning
      • Thermal shutdown
    • Fully protected driver for external MOSFETs in H-bridge configuration
    • Two 5 V voltage regulators for microcontroller and peripheral supply
    • Programmable reset generator for power-on and undervoltage
    • Configurable window watchdog
    • LIN 2.2a compliant (SAEJ2602 compatible) transceiver
    • Separated (Isolated) fail-safe block with 2 LS (RON = 1 Ω) to pull down the gates of the external HS MOSFETs
    • Thermal clusters
    • A/D conversion of supply voltages and internal temperature sensors
    • Embedded and programmable VS duty cycle adjustment for LED driver outputs
