Door actuator driver

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). Also all diagnostic information is available via SPI read.

Key Features

  • 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 VS current 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 Rdson down 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
