Leading professional analog and mixed signal semiconductor manufacturers sisi-en Technology (SI-EN Technology) recently released 10 output RGB a music synchronous respiratory function driver chip N3189. This chip is suitable for mobile phone, MP3/MP4 player, portable GPS navigation handheld electronic devices, light emitting system of such products help produce more bright color bright lights, attract the attention of consumers and improve product positioning.
SN3189 can work in System Free mode: the system initialization is complete, the chip can be cycle operation, external control bus can be released, will not take up system resources. This makes the design of the product lighting effect becomes more simple, manufacturers do not need to modify a large number of software programs, without the need to take advantage of the external system resources can easily achieve beautiful and delicate sound and light synchronization.
SN3189 chip with built-in ADC analog-to-digital conversion, memory registers and intelligent digital signal processing module, the 10 output ports can be independently controlled SN3189 chip. One of the 6 RGB driver, each drive start and stop time, slope and brightness of the current can be initialized through the control port settings.
SN3189 drive mode can be synchronized with the music all the breath; 6 RGB output support external 256 brightness independent control, output current of each path can be as high as 40mA, parallel LED light.
SN3189 mainly has the following characteristics:
1 System Free model, built in Memory, only one initialization
2.10 outputs, each individually controllable
3 integrated 6 RGB breathing lamp driver, each way of internal control and external control, internal control of breathing without taking the external system resources
4 integrated Top down scan mode and synchronous music breathing mode
5 audio amplifier gain can be set inside
In order to meet the design requirements of product diversity, SI-EN also simultaneously launched 3 RGB breathing light without music synchronization drive chip SN3101; 6 RGB breathing light without music synchronous drive chip SN3103.
SN3189 operating voltage range of 3.0V-5.5V, the operating temperature range to achieve - Extended Industry Standard 40 DEG to +85 DEG, with slender QFN20 (3x3) package, has been in production, you can batch delivery.
SN3101 operating voltage range of 3.0V-5.5V, which can drive 3 RGB breathing lights, each at the same time support an internal control and external programming 256 levels of brightness control, working temperature range to achieve - Extended Industry Standard 40 DEG to +85 DEG, with slender DFN10 (3 x 3) package, has you can batch production, delivery.
SN3103 operating voltage range of 3.0V-5.5V, which can drive 6 RGB breathing lights, each at the same time support an internal control and external programming 256 levels of brightness control, working temperature range to achieve - Extended Industry Standard 40 DEG to +85 DEG, with slender QFN20 (4 x 4) package, has you can batch production, delivery.
