L99DZ80 multifunctional door zone driver

ST's L99DZ80 is the first multi-functional door-zone driver with integrated electric-window control. This IC embeds an SPI-programmable slew-rate control IP that can drive 4 external MOSFETs in a half-bridge configuration dedicated to PWM (Pulse Width Mode)-driven electric-window applications.

Other features include six bridges for double door-lock control, mirror fold, and mirror-axis control, together with a high-side driver for mirror defroster, bulbs and LEDs. The device also integrates a control block with an external MOS transistor for charging and discharging of electrochromic (dimmable) mirror glasses.

It offers the following key benefits:

  • Reduces bill of materials for door zone electronics
  • Removes the need for mechanical relays, and for expensive EMC countermeasures
  • Offers a smoother and quieter car-window operation
