TM512ACE DMX512 LED Driver IC
Description:
The TM512ACE is a high-performance DMX512 differential parallel protocol LED driver IC designed for precision control in lighting applications. It features 16-bit grayscale control and enhanced 2.2 gamma correction, offering improved visual perception for the human eye. With three high-precision constant current output channels and the ability to decode DMX512 signals with transmission rates from 200Kbps to 1000Kbps, the TM512ACE provides exceptional adaptability and flexibility for lighting systems.
This LED driver IC is fully compatible with and extends the DMX512 protocol, supporting up to 4096 channels without the need for rate configuration. The built-in EEPROM allows for internal storage and eliminates the need for external components. Additionally, the TM512ACE supports online programming via AB-line, allowing for one-time automatic programming, and it offers a dual-backup mode for address storage, ensuring that even with EEPROM damage, the address is not lost.
The IC offers high-speed performance, with a screen refresh rate up to 2KHz, and 80mA current output per channel, making it ideal for demanding applications in stage lighting systems, building decoration, and video wall displays. Multiple constant current output channels can be short-circuited to increase the current-driving capability, making it highly adaptable to various lighting setups.
The TM512ACE is designed with industrial-grade reliability, ensuring stable performance even in harsh environments. It operates efficiently with 5V power supply regulation and includes various built-in protections, such as the 80ns output channel delay to reduce current surge interference.
