1.Feature:
Built-in power regulator voltage stabilizing function, input power supply voltage: 5V~36V
Compliant and extended DMX512 (1990) protocol
Differential signal transmission rate:200kbps~750kbps
The differential parallel signal transmission, support maximum 4096-channel addressing.
Customizing OUT R/G/B/W port the default display effect
The first chip lights up in red and the remaining chips light in green when succeeding writing address
The first chip lights up in red and the remaining chips light in the preset lights when succeeding writing parameters.
The first chip lights in red and the remaining chips light in yellow when succeeding writing current gain
The first chip will light up in red, and the remaining light in purple after writing the automatic addressing/automatic addressing/adaptive function successfully
OUT port opening width compensation 7 levels adjustable
Address line open circuit self-check function
No input signal for 2 seconds, switch the default display effect or maintain the last frame display state.
Built-in 1/2/3/4 channel selection function
OUT R/G/B/W each 5 bits current gain adjustment
OUT R/G/B/W withstand voltage: 40V
Built-in OTP
Package: SSOP10
2.Description:
The SM18512PS is a 4-channel, parallel differential signal transmission LED driver, It is compatible and extends the DMX512 (1990) communication protocol. It has a variety of characteristics, including signal differential transmission, with a lot of load points, strong anti-interference ability, far transmission distance etc.
OUT R/G/B/W port output current 18mA and 32-level current gain of OUT R/G/B/W can be set separately through the controller parameters. At the same time, the PWM refresh rate of OUT port 4KHz greatly improves the refresh rate of the screen.
