G5031Q51D
12-Channel, 16-Bit, Enhanced Spectrum, PWM, RGB, LED Driver with 3.3-V Linear Regulator
The G5031 is a 12-channels, constant-current sink driver, which is designed for RGB LED cluster lamp applications using internal Pulse Width Modulation (PWM) control with 16-bit color depth. Each output channel has individually adjustable currents with 65536 PWM grayscale (GS) steps. Also, each color group can be controlled by 128 constant-current sink steps with the global brightness control (BC) function. GS control and BC are accessible via a two-wire signal interface. The maximum current value for each channel is set by a single external resistor. All constant-current outputs are turned off when the IC is in an over-temperature condition.
