Overview
First, The outlines.
Three channels LED driving control dedicated circuit TM1804 TM1804 is a three channels LED(light-emitting diode monitor)driving control dedicated circuit,it’s inside intergrated with MCU digital interface 、digital latch、 LED high voltage driving circuit and so on.
Through the contoring of the outside MCU then the Chip ’ single grey will be achieved.
The cascade controling make the outdoor big colored screen ’ lattice come true.
This product which is packaged by SOP8 has perfect performance and trustworthy quality .
Second, The characteristics ·With high voltage power CMOS crafts ·The withstanding voltage of output interface is 24v ·The working voltage of the chip is 5v-24v ·the grey calibration circuit(256 grade grey ajustment) ·serial interface cascade interface ·Vibration mode：RC inside vibrating and Clock synchronization according the signals from the date line.
,after receiving all of the statistics from the unit then when finished the date shaping it can automatically send out through the ouput interface .
·power on reset inside ·PMW controlling side can make the 256 grade adjustment.
Scanning frequency is more than 400hz/s ·It can make the datas’ receiving the decoding come through one signal wire.
· When the refresh rate is 30 FPS the next cascade in low-speed mode is more than 512 spots,in the high –speed mode it is more than 1024 spots.
·Package type:SOP8 ·Data sending speed can reach 400Kbps and 800Kbps separately two modes.
