BROADCHIP launched a BCT3288 16-channel constant current LED driver for the portable product market. The 64-level constant current output of each channel is convenient and controllable for mobile phones, digital photo frames, notebooks and small appliances. Portable products bring the effect of colorful LED lights, which complements the gaps in the industry. This further expands Broadchip's LED driver product lineup.
"As consumers increasingly demand the appearance of portable products such as mobile phones, the current industry is generally a multi-channel unified current level LED driver output, this ordinary LED effect similar to the marquee function is not attractive On this basis, Guangxin Electronics has completely defined a new effect of the colorful light drive solution." CTOJerry Dai of Guangxin Electronic Technology Co., Ltd. said, "The BCT3288 is very suitable for white and color LED applications because there are 16 output channels. Each channel can support up to 40mA output capability, each channel can have 64 different levels of current output. The SPI protocol can determine any current output of any channel, which provides great flexibility for LED output and can demonstrate a lot of Colorful effects, such as: horse racing, breathing, comet smear and other product designers can imagine the LED effect."
The BCT3288 has 16 independent high-precision current sources with a current sink capability of 40mA per current source. The external hardware circuit of the LED driver is simple. Only one filter capacitor and one resistor for setting the current are needed. The maximum drive current capability of each driver is set by an external resistor. The operating voltage range is 2.7 ~ 5.5V, VIH is 0.6VDD, so it can be well applied to the 2.8V VIO mobile phone platform.
The BCT3288 is a pollution-free, lead-free, environmentally friendly product with an extended industrial temperature range of -40°C to +85°C and is available in a QFN-24 (4mm × 4mm) package.
