Introduction
TM1805 is a self-controlled LED pattern display driver IC with a built-in oscillator, 3 RGB output ports, requiring no MCU control to achieve colorful lighting effects with three selectable modes. It features a synchronous display interface that can sample 50Hz mains frequency via a single resistor as the sync signal input. The IC integrates built-in 24V and 5V Zener regulators, offering a simplified peripheral circuit design, excellent performance, and reliable quality — suitable for decorative string lights and point light sources.
Features
- High-voltage power CMOS process
- Built-in 24V and 5V Zener diodes
- 3 RGB output ports
- RGB constant-voltage output, 24V rated voltage
- Three variation mode settings
- Synchronous frequency input for inter-chip synchronized display
- VDD typical operating voltage: 5.0V
- Package: SOP8, DIP8
Applications
- LED effect decoration
- Point light source
- Color-changing lights
