TM(Shenzhen Titan Micro Elec) TM512AD

TM512AD is a DMX512 differential parallel protocol LED driver IC, supporting selectable 1/2/3/4 channel high-precision constant current output with 65536 grayscale levels. The decoding technology precisely decodes DMX512 signals with full compatibility and extension of 512 protocol signals, providing fully adaptive decoding for DMX512 signals with transmission frequencies between 200K and 1000kbps — no speed configuration required — with addressability up to 4096 channels. Built-in E2PROM eliminates external components. Utilizing AB-line online code writing, luminaires can be programmed without connecting a dedicated code writer, offering simple wiring and flexible configuration. Parameters (power-on lighting state, field selection, current adjustment) can be configured via E2. The IC provides 4 high-precision constant current output channels with withstand voltage above 28V and output up to 64mA per channel, with independent 64-level software-adjustable current per channel and a dedicated 4-color current setting mode. 4K high port refresh rate significantly improves frame refresh performance. Primarily designed for architectural decoration and stage lighting LED illumination systems, it is ideal for parallel-connected LED lighting systems where a fault in any single IC has no impact on the normal operation of others, ensuring simple and convenient maintenance.
