Display and Lighting

ADI offers LED drivers that range from automotive to display and keypad LED-backlighting applications. Products like the AD8240, designed for automotive applications, both drive and monitor the LED assembly. The AD8240 lowers system cost by reducing the complexity associated with LED driving, includes overcurrent protection, and is available in a MSOP package. The ADP8860/70 charge pump LED drivers are designed for driving up to seven white LEDs in parallel and has a built-in controller for automatic light adjustment based on ambient conditions. The ADP8860/70 can independently control each LED sink allowing one LED backlight driver to be used for multiple lighting requirements such as LCD backlight and keypad backlighting at the same time. These intelligent state-machine products improve battery life by reducing processor interaction and improve time to market by reducing software complexities.
