STMicroelectronics Unveils Industry-First Car-Door Controller IC with Integrated Window Control
STMicroelectronics today introduced the market’s first multi-functional door-zone driver with an integrated electric-window control. This innovative chip, which reduces bill-of-material costs and offers new levels of passenger comfort, has already been selected for broad adoption at a leading German car manufacturer.
TodaST’s L99DZ80 embeds an SPI-programmable slew-rate1 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.
ST is the world’s largest supplier of car-door electronics, with more than 100 million door-actuator devices shipped over the past ten years. Designed for state-of-the-art automotive door-module applications, ST’s market-proven devices are renowned and recognized for their scalability, small size, advanced power-management functionality, and superior thermal performance.
The newest addition to ST’s family of microcontroller-driven multi-functional car-door actuator drivers, the L99DZ80 is available in volumes. For pricing options, please contact your ST sales office.
