Overview

TM1809 is a 9-channel LED driver control IC, integrating an MCU digital interface, data latches, and high-voltage LED driver circuits. Individual brightness control and cascade control of the chip are achieved via an external MCU, enabling color dot-matrix light control for outdoor large-screen displays. This product offers excellent performance and reliable quality.

Applications

Point light source
Guardrail tube
Flexible light strip
Indoor/outdoor large display screen

Key features

High-voltage power CMOS process
Output port voltage rating: 30V
VDD with integrated internal 5V Zener diode
External series resistor on VDD pin, supporting 6~24V input voltage
Brightness adjustment circuit, 256-level brightness control, equivalent to 1024 levels at low brightness
Single-wire serial cascade interface
Oscillation method: built-in RC oscillator with clock synchronization based on data line signals; after receiving data for the current unit, automatically reshapes subsequent data and transmits it to the next stage via data output — no signal distortion or attenuation over extended cascade distances
Built-in power-on reset circuit
V PWM control pin supports 256-level adjustment with scan frequency ≥400Hz
Data reception and decoding via single signal line
At 30 frames/s refresh rate: cascade count ≥540 points in low-speed mode and ≥1080 points in high-speed mode
Data transmission speed: 400Kbps or 800Kbps dual-mode
Package types: SOP14, DIP14
