The IC electrical parameters (TA=-20 to +70℃, VDD=4.5 to 5.5V, VSS=0V)
Single point single control: realize color change and infinite cascading to the lower level through a communication protocol. Lamp driver in one: The light-emitting chip and driver communication IC are combined into one to form a new light source, requiring fewer passive components. Uniform light source: low light consumption, high brightness, and delicate light source effect. Intelligent external control: Write data through an external controller to achieve changes in internal communication IC effects. Convenient connection: Various peripherals realize wireless drive control connection according to the protocol (such as mobile phone APP/infrared controller, etc.). Lower energy consumption: powerful functions, lower power consumption, greener and more environmentally friendly, and longer service life.
