SI-EN Unveiled System-Free Audio-Synchronized Breathing LED Driver SN3189

 
The leader in analog mixed-signal semiconductor industry, Si-En Technology recently unveiled another new product C an audio-synchronized breathing function RGB LED driver SN3189 with 10 outputs. This IC will have applications in mobile phones, MP3/MP4, GPS and etc. handheld devices. It will help to enhance those products display to generate more active colorful luminance to attract consumers eyes and increase product''''''''''''''''s value.
 
SN3189 can work in system-free mode. After initialization, the IC can work on programmed pattern periodically with no need of external control, thus release the system resources. This will make product light effect design much simpler, no need to modify software all the time. It is much easier to realize sound-light synchronized effect without occupying external resources.
 
SN3189 has ADC converter, memory register and intelligent digital process module, its 10 outputs can be controlled independently. There are 6 channel of RGB driving, every channels start, stop, slope and output current can be initially programmed through interface control input,
 
SN3189 has the following features:
1.       Has system-free mode, internal memory, only need one-time initialization.
2.       10 independently controllable output channels.
3.       6 channel RGB breathing LED driving, each channel can be controlled internally and externally.
4.       Top-down scan mode and audio-synchronization mode.
5.       Audio gain can be adjusted via internal set-up.
 
For product versatility design need, Si-En also push to the market a 3-channel no audio-sync RGB LED driver SN3101, a 6-channel no audio-sync RGB LED driver SN3103.
 
SN3189 power supply range is 3.0V to 5.5V, operating temperature range from C40 to +85, using small package of QFN20, has been in production.
 
SN3101 power supply range is 3.0V to 5.5V, can drive 3 channel RGB LEDs, each channel support one-time-program control internally and 256 brightness level control externally. Operating temperature range from C40 to +85, using small package of QFN20, has been in production.
 
SN3103 power supply range is 3.0V to 5.5V, can drive 6 channel RGB LEDs, each channel support one-time-program control internally and 256 brightness level control externally. Operating temperature range from C40 to +85, using small package of QFN20, has been in production.
