DS3882E+C, Dual Channel CCFL Controller

Semiconductors - ICs\Power Management ICs - PMIC\Drivers & Controllers\Ballast Controllers The DS3882E+C is a dual channel cold cathode fluorescent lamp (CCFL) controller in 28 pin TSSOP package. It is used for applications that provide up to 300: 1 dimming. It is ideal for driving CCFLs used to backlight liquid crystal displays (LCDs) in navigation and infotainment applications and CCFLs used to backlight instrument clusters. The DS3882 is appropriate for use in marine and aviation applications. It has EMI suppression functionality and provides lamp current overdrive mode for rapid lamp heating in cold weather conditions. The device supports configurations of 1 or 2 lamps with fully independent lamp control and minimal external components. Control of DS3882 after initial programming setup can be completely achieved through I2C software communication. Many DS3882 functions are also pin controllable if software control is not desired. It has accurate (±5%) independent onboard oscillators for Lamp frequency (40KHz to 100KHz) and DPWM burst dimming frequency (22.5Hz to 440Hz). • Supply voltage range from 4.75V to 5.25V • Operating temperature range from -40°C to 105°C • Supply current of 12mA and SCL clock frequency of 400KHz • Analogue and digital brightness control • Per channel lamp fault monitoring for lamp open, overcurrent, failure to strike & overvoltage • Status register reports fault conditions • Multiple DS3882 controllers can be cascaded to support applications requiring more than 2 lamps • Optional spread spectrum lamp clock reduces EMI • Low power standby mode • 8byte NV user memory for storage of serial numbers and date codes
