The DS3881 is a single-channel cold-cathode fluorescent lamp (CCFL) controller for automotive applications that provides up to 300:1 dimming. It is ideal for driving CCFLs used to backlight liquid crystal displays (LCDs) in navigation and infotainment applications and for driving CCFLs used to backlight instrument clusters. The DS3881 is also appropriate for use in marine and aviation applications. The DS3881 features EMI suppression functionality and provides a lamp current overdrive mode for rapid lamp heating in cold weather conditions. The DS3881 supports a single lamp configuration with fully independent lamp control and minimal external components. Multiple DS3881 controllers can be cascaded to support applications requiring more than one lamp. Control of the DS3881, after initial programming setup, can be completely achieved through I2C* software communication. Many DS3881 functions are also pin-controllable if software control is not desired.
