STMicroelectronics L99DZ80/81 Door Actuator Drivers

STMicroelectronics L99DZ80/81 Door Actuator Drivers are designed for state-of-the-art automotive door-module applications. They employ a scalable actuator-driving concept, which includes package and software compatibility with the wide variety of door electronics used by the industry. The actuator drivers support all regular door-module loads such as window lifting, lock motors, mirror leveling, mirror retraction, defrosters, and several lighting functions from incandescent bulbs to LEDs.

STMicroelectronics L99DZ80EP Door Actuator Driver 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.

Features
  • One full bridge for 6A load (RON = 150mΩ)
  • Two half bridges for 3A load (RON = 300mΩ)
  • Two half bridges for 0.5A load (RON = 1600mΩ)
  • One high-side driver for 5A load (RON = 100mΩ)
  • One configurable high-side driver for up to 1.5A (RON = 500mΩ) or 0.35A (RON = 1600mΩ) load
  • One configurable high-side driver for 0.7A (RON = 800mΩ) or 0.35A (RON = 1600mΩ) load
  • Two high-side drivers for 0.5A load (RON = 1600mΩ)
  • Programmable softstart function to drive loads with higher inrush currents as current limitation value
  • Very low VS current consumption in standby mode (IS < 6μA 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 6V
  • 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 (STSPI 3.1)
  • Control block for electrochromic element
  • Electrochromic element can be negatively discharged
  • Prepared for additional fail-safe path for H-bridge

Applications
  • Door actuator driver with 6 bridges for double door lock control, mirror fold and mirror axis control, high-side driver for mirror defroster, bulbs and LEDs
  • Control block with external MOS transistor for charging / discharging of electrochromic glass
  • Motor bridge driver
  • H-bridge control for external power transistors
