DS3882E+C

Overview

The DS3882E+C is a dual-channel automotive cold cathode fluorescent lamp (CCFL) controller manufactured by Analog Devices Inc. under the Maxim Integrated brand. Designed for surface-mount applications, it operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range from -40°C to +105°C. The device features a TSSOP-28 package and draws a typical supply current of 12 mA. It functions as a driver IC specifically for CCFL displays, providing control signals for dual backlight channels in automotive environments.

Feature Summary

• Dual-channel control architecture designed for simultaneous management of two independent CCFL backlight circuits.
• Automotive-grade thermal rating ensuring reliable operation across extended industrial temperature ranges.
• Integrated dimming capability allowing for adjustable brightness control of connected fluorescent lamps.

Applications

• Automotive instrument cluster backlighting systems
• Vehicle infotainment display illumination
• Dashboard indicator lighting control

Procurement Notes
