The single-wire transmission protocol lighting solution mainly consists of the corresponding protocol chip, lamp beads and a few resistors and capacitors. It can be designed as single-color, cold and warm dual-color light source, three-color or four-color full-color point light source, strip light, line light, etc. according to actual needs.
TM1814 is a single line return 1 code protocol LED constant current driver IC with internal control synchronization function. The chip provides four high-precision constant current output channels with withstand voltage up to 28V, output current can be set by software (6.5--38mA), a set of constant current setting and PWM setting data can be input by external controller to realize various kinds of display, when the signal input is disconnected to achieve synchronous fixed seven-color pattern change, to prevent the chip from damage to the subsequent cascade chip does not work. Suitable for guardrail tube, point light source and other LED decorative products.
