Single-Channel Automotive CCFL Controller  
DS381  
General Description  
Features  
♦ Single-Channel CCFL Controller for Backlighting  
The DS3881 is a single-channel cold-cathode fluores-  
cent 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 dri-  
ving CCFLs used to backlight instrument clusters. The  
DS3881 is also appropriate for use in marine and avia-  
tion applications.  
LCD Panels and Instrument Clusters in  
Automotive Navigation/Infotainment Applications  
♦ Minimal External Components Required

♦ I C Interface  
♦ Per-Channel Lamp-Fault Monitoring for Lamp-  
Open, Lamp-Overcurrent, Failure to Strike, and  
Overvoltage Conditions  
The DS3881 features EMI suppression functionality and  
provides a lamp current overdrive mode for rapid lamp  
heating in cold weather conditions. The DS3881 sup-  
ports a single lamp configuration with fully independent  
lamp control and minimal external components.  
Multiple DS3881 controllers can be cascaded to sup-  
port applications requiring more than one lamp. Control  
of the DS3881, after initial programming setup, can be  
♦ Status Register Reports Fault Conditions  
♦ Accurate ( 5%) Independent On-Board Oscillators  
for Lamp Frequency (40kHz to 100kHz) and DPWM  
Burst-Dimming Frequency (22.5Hz to 440Hz)  
♦ Lamp and DPWM Frequencies can be  
Synchronized with External Sources to Reduce  
Visual LCD Artifacts in Video Applications  
♦ Spread-Spectrum Lamp Clock Reduces EMI

completely achieved through I C software communica-  
tion. Many DS3881 functions are also pin-controllable if  
software control is not desired.  
♦ Lamp Frequency can be Stepped Up or Down to  
Move EMI Spurs Out of Band  
♦ Lamp Current Overdrive Mode with Automatic  
Turn-Off Quickly Warms Lamp in Cold  
Temperatures  
♦ Analog or Digital Brightness Control
