TM1804 LED decoration driver IC(10000pcs/lot)

 Description:

  TM1804 is 3 channels (emitting diode) LED display driver control circuit. Its internal integration has special MCU digital interface, data latches, LED high-voltage driver circuits, etc. It realizes the outdoor light color dot matrix control through the single gray and cascade control by peripheral MCU. The IC adopts high voltage power CMOS technology, 24V output port voltage, gray adjustment circuit(gray 256 can be adjustable), professional singleline serial interface and cascade interface pact. It can finish receiving and decoding of data through a signalwire. Built-in RC oscillation, make the clock synchronization according to the data signals. After finishing this unit, the data can be automatically sort out and then through the data output terminal.Its internal has power on reset circuit and low voltage reset circuit, PWM control electric circuit reset the client can achieve 1024, scan frequency modulation is not less than 400hz/s. When the transmission cable distance between chips is less than 1 metre and the cascade number is not less than 512. When the transmission cable distance between chips is less than 3 metres and the cascade number is not less than 256. The data sending speed can reach 400Kbps. Its encapsulation is SOP8.

features:

1. 3 channels constant voltage.

2. Single cascade.

3. Gray 256 can be adjustable.

4.Work voltage is 6V~24V.
