TM512AB3 DMX512 LED Driver Chip

TM512AB3 DMX512 LED Driver Chip

Product Description
The TM512AB3 is a high-performance DMX512 single-wire parallel protocol LED driver chip that offers precision constant current output across 3 channels. With advanced decoding technology, the TM512AB3 accurately decodes DMX512 signals and is fully compatible with and extendable for the DMX512 protocol. It automatically adapts to DMX512 signal transmission speeds from 200Kbps to 1000Kbps without the need for any speed adjustments. The chip supports up to 4096 addressable channels.

The TM512AB3 features an integrated EEPROM, eliminating the need for external components. It also supports online address writing, which allows for easy programming of multiple chips in series, with a distance of up to 100 meters between each chip. This feature ensures that programming can be done quickly and efficiently, saving time and reducing complexity.

With 3 constant current output channels rated for up to 26V and 18mA, the TM512AB3 provides high output precision and a high port refresh rate for significantly improved visual performance. It is primarily designed for architectural decoration and stage lighting applications, making it ideal for LED lighting systems that require parallel connections. Importantly, a malfunction in one chip will not affect the operation of others, making maintenance straightforward and reliable.
