  • The L99DZ80EP is a microcontroller driven multifunctional door actuator driver for automotive applications. Up to five DC motors and five grounded resistive loads can be driven with six half bridges and five high-side drivers. Four external MOS transistors in bridge configuration can be driven. An electrochromic mirror glass can be controlled using the integrated SPI-driven module in conjunction with an external MOS transistor. The mirror glass can also be discharged through a negative supply. The integrated SPI controls all operating modes (forward, reverse, brake and high impedance). All diagnostic information is available via SPI read.

    Key Features

    • AEC-Q100 qualified
    • One full bridge for 6 A load (RON= 150 mΩ)
    • Two half bridges for 3 A load (RON= 300 mΩ)
    • Two half bridges for 0.5 A load (RON= 1600 mΩ)
    • One high-side driver for 5 A load (RON= 100 mΩ)
    • One configurable high-side driver for up to 1.5 A (RON= 500 mΩ) or 0.35 A (RON= 1600 mΩ) load
    • One configurable high-side driver for 0.7 A (RON= 800 mΩ) or 0.35 A (RON= 1600 mΩ) load
    • Two high-side drivers for 0.5 A load (RON= 1600 mΩ)
    • Programmable softstart function to drive loads with higher inrush currents as current limitation value
    • Very low VScurrent consumption in standby mode (IS< 6 μA typ; Tj≤ 85 °C)
    • Current monitor output for all high-side drivers
    • Central two-stage charge pump
    • Motor bridge driver with full Rdsondown to 6 V
    • Device contains temperature warning and protection
    • Open-load detection for all outputs
    • Overcurrent protection for all outputs
    • Separated half bridges for door lock motor
    • Programmable PWM control of all outputs
    • STM standard serial peripheral interface (ST-SPI 3.1)
    • Control block for electrochromic element
    • Electrochromic element can be negatively discharged
    • Prepared for additional fail-safe path for H-bridge
