BROADCHIP TECHNOLOGY GROUP Co., Ltd. (BROADCHIP TECHNOLOGY GROUP Co., Ltd.) is an integrated circuit design company established by a Chinese entrepreneurial team in Silicon Valley, USA. In 2007, it established a wholly-owned subsidiary in Shanghai: BroadChip Electronic Technology (Shanghai) Co., Ltd. The company's goal is to create a world-renowned enterprise with core competitiveness by introducing advanced integrated circuit design technology and innovative concepts from Silicon Valley, USA, combined with the use of a large number of outstanding scientific and engineering talents in China. BroadChip Electronics' main business will focus on the design, development and sales of high-performance, high-quality, low-power, and cost-effective analog and mixed integrated circuit chips. Its products will be widely used in computers, communications, automotive electronics, and popular civilian electronic products. The company focuses on the design, development and sales of high-performance, high-quality analog and mixed-signal integrated circuit chips and acceleration sensor chips. It adopts the internationally common model of fabless production design companies, outsourcing wafer processing and packaging testing, and focusing on product design, development and sales.
BCT3299 has built-in RAM, and it can realize autonomous breathing and flashing with just one programming. When programming, determine the combination of frequency, level number, channel, etc. They are all independent of each other. In breathing mode, the starting breathing point of each channel can be set, so that a staggered breathing effect can be achieved. When entering audio mode, there are two functions, one is that the software can determine any channel to breathe with music, and the other is to output PWM or level control signals with music, drive motors, etc., and realize functions such as jumping with music.
The chip shutdown current of less than 2uA effectively extends the battery life. BCT3299 is a pollution-free, lead-free and environmentally friendly product with an extended temperature range of -40℃ to +85℃, and adopts a QFN-24 (4mm×4mm) package with a thickness of 0.75mm.
characteristic:
? 16-channel constant current drive, each channel has a maximum output current capacity of 30mA, REXT resistor sets the maximum output current? Each channel has 256 levels of current, which can be controlled independently or in multiple combinations through SPI. ? Built-in POR power-on reset function? Chip high level recognition minimum value 1.4V? LED common anode connection? Chip can recognize frequency <20MHz? Music follow-up PWM output with four output frequencies to choose from? 2.7V ~ 5.5V wide power supply range? QFN-24 (4mm x 4mm) package
