9-channel LED driver control IC
T M1809
1. 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 Use high-voltage power CMOS process
z Output pin tolerance voltage is up to 24V
z Input voltage can support 6 ~24V via outside resistance connected to chip VDD pin
z Build-in stabilized voltage supply circuit
z Brightness adjustment circuit(256 level)
z Signal line for series cascade interface
z Oscillation mode：Built-in double RC oscillator and clock synchronization
z Built-in power-on reset circuit
z PWM control side can achieve 256 adjustment, scan frequency not less than 400hz / s
z 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
z Data transmission speed have two selected mode ( 400Kbps and 800Kbps )
z SOP14
