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
