Product Introduction
LED Colorful Light - TF-S166 is a dedicated output channel for a 3-channel RGB LED driver circuit. It also includes internal intelligent digital port data latching and signal shaping amplification driver circuits. TF-S166 uses a single NZR communication mode. After the chip is powered on and reset, the DIN port receives data from the controller. The first IC captures the initial 24-bit data and sends it to the internal data latch. Another data is shaped by the internal signal shaping amplification circuit and sent to the next cascaded IC via the DO port. After each chip transmission, the signal is reduced by 24 bits. The IC uses automatic shaping transmission technology, so the number of cascaded chips is not limited by signal transmission, only by the signal transmission speed. The IC's data latching depends on the received 24-bit data to generate different duty cycle signals at the IO_R, IO_G, and IO_B ports. When a reset signal is input at the DIN port, all chips synchronously send the received data to each segment.After the reset signal ends, it will receive new data again. Before receiving a new reset signal, the control signals at the IO_R, IO_G, and IO_B ports remain unchanged. The IC sends the correctly received PWM data to the IO_R, IO_G, and IO_B ports after receiving a low-voltage reset signal, with a duration of at least 24us.
