Download datasheet: TM1809

TM1809 is a 9-channel LED driver control IC. Internal integrated with MCU digital interface,  
data flip-latch, LED high voltage driver and so on .Through the external MCU control, the chip can  
achieve separate luminance, and through cascade control can achieve outdoor large-screen color  
dot-matrix light-emitting control. TM1809 have excellent performance and high reliability.


Feature
- Use high-voltage power CMOS process  
- Output pin tolerance voltage is up to 24V  
- Input voltage can support 6 ~24V via outside resistance connected to chip VDD pin  
- Build-in stabilized voltage supply circuit
- Brightness adjustment circuit(256 level)  
- Signal line for series cascade interface  
- Oscillation mode:Built-in double RC oscillator and clock synchronization  
- Built-in power-on reset circuit  
- PWM control side can achieve 256 adjustment, scan frequency not less than 400hz / s  
- When the refresh rate is 30 frames/ s, the number of cascade is not less than 540 on  
low-speed mode. And it is not less than 1080 on high-speed mode  
- Data transmission speed have two selected mode ( 400Kbps and 800Kbps )   
- SOP14
