DESCRIPTION
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. 2. Feature z z z z z z z z z z z z 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 3.
