TM512BCE DMX512 LED Driver IC with 16-bit Grayscale, Gamma 2.2
Description
The TM512BCE is a DMX512 differential parallel protocol LED driver IC with 16-bit grayscale and enhanced Gamma 2.2 correction for better visual perception. It features 3 high-precision constant current output channels and can decode DMX512 signals with transmission rates from 200Kbps to 1000Kbps, without the need for rate adjustments. Supporting up to 4096 channels, the TM512BCE has built-in EEPROM, eliminating the need for external memory, and supports online code writing. The chip provides three 30V-rated output channels with a maximum current of 80mA, with current adjustable via external resistors. Ideal for architectural lighting and stage lighting systems, the TM512BCE ensures that a failure in one chip doesn’t affect the others, making it easy to maintain.
