Car-Door IC Integrates Window Control

The L99DZ80 is allegedly the first multi-functional door-zone driver with integrated window control. It embeds an SPI-programmable slew-rate control IP that drives four external MOSFETs in a half-bridge configuration dedicated to PWM-driven window apps. Other features include six bridges for double door-lock control, mirror fold, mirror-axis control, and 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. STMICROELECTRONICS, Lexington, MA. (888) 787-3550.
