Cxle8784p is a parallel differential transmission four channel LED driver output control chip which is compatible with and extends DMX512 (1990) signal protocol

The chip contains power supply voltage stabilizing circuit, time-based circuit, 485 module, signal decoding module, data buffer, built-in oscillator, four channel constant current driver with a default output current of 17mA. At the same time, the user can also adjust the required current through the external next resistor. The SPWM gray level is 65536, and the SPWM output supports the polarity reversal at the output out end. The built-in EEPROM stores the chip address, and the data bus automatically writes the address once, which can exit the address writing state online without power on again.
