1.Feature :
Built-in power clamp module, input power voltage: 5~24V
The default constant current value of OUT R/G/B/W is 19mA
OUT R/G/B/W power-on state: closed
OUT R/G/B/W port withstand voltage 26V
OUT R/G/B/W output gray level: 65536 levels (GAMMA correction)
OUT R/G/B /Weach 4bits current gain adjustment bit
Patented SM-PWM control technology, refresh rate is up to 4KHz
Synchronous refresh for the same frame display data
Adopt single-line return-to-zero code SID data protocol
Data serial cascade transmission, strong anti-interference ability
Signal transmission rate: 800Kbps
Package: SOP8
2.Description :
SM16804PB is a four-channel LED driver control chip, using single-wire return-to-zero code SID data protocol.
The default output current of SM16804PB is 19mA, and the current can be set to 1.8mA~19mA through the current gain adjustment function, a total of 16 current gain levels.
SM16804PB outputs 65536 gray scales (GAMMA correction), which makes the display effect more delicate and smooth.
The refresh rate is as high as 4KHz, which solves the problem of dark stripes on the shooting screen.
3. The protocol Please check SM16804PB datasheet.
