Product Description
TM512AB4 is a DMX512 single-wire parallel protocol LED driver chip, offering 4 high-precision constant current output channels. This chip accurately decodes DMX512 signals and is fully compatible with the 512 protocol. It can decode DMX512 signals at transmission rates from 200Kbps to 1000Kbps without requiring speed adjustments, with addressing capability of up to 4096 channels. The TM512AB4 features built-in E2PROM, eliminating the need for external memory, and supports online programming. You can daisy-chain multiple TM512AB4 chips for simultaneous programming, with a maximum cable length of 100 meters between chips.
This chip provides 4 high-precision constant current output channels with a voltage tolerance of up to 26V and a preset 18mA current output. The high port refresh rate improves the frame rate significantly. It is ideal for LED lighting systems that require parallel connections, such as architectural decorations and stage lighting effects. The system is designed for ease of maintenance, ensuring that any failure in one chip does not affect the operation of others.
Key Features:
- Protocol Compatibility: Supports and extends DMX512 (1990) protocol.
- Control Method: Single-wire parallel, with up to 4096 channels of addressing.
- High-Speed Decoding: Supports DMX512 transmission rates of 200Kbps to 1000Kbps with automatic adaptation.
- Built-in E2PROM: No need for external E2PROM.
- Easy Programming: Supports online programming with a dedicated address line; no need to power down the system after programming.
- Advanced Interference Protection: Features 8 anti-interference and error-checking designs, ensuring reliable operation even in noisy environments.
- Low Voltage Operation: Works stably with a voltage as low as 2.6V.
- High Refresh Rate: 3.6KHz for smoother visual effects.
- Industrial-Grade Design: Ensures long-lasting, stable performance in demanding environments.
Applications: TM512AB4 is perfect for point light sources, linear lights, wall washers, stage lighting systems, indoor and outdoor video walls, and decorative lighting systems.
