GS8206 Datasheet Text
GS8206 3 channel constant current LED driver
General Descriptions
The GS8206 is a 3-channel constant current LED drive with resumable data transfers and internal display patterns. There are three open-drain constant current outputs, with a build-in PWM of grayscale. The range of input power is from +5V to +24V, and voltage-endurance of LED port is +24V. There is a built-in 12bits GAMMA correction module. PWM maximum refresh frequency is 8kHz. The GS8206 use the e-RZ (extended return to zero code) as the signal transmission mode, which can control the output current channel by channel and cascade infinitely. GS8206 provides two-signal data input as redundant control, which ensures the transmission of the signal if any single chip damages. In the absence of signal input, GS8206 displays the built-in display patterns that is suitable for those applications without a controller. There is the built-in power-on and power-off protection in the drive, which can enhance the service life of the chip. It also has the automatic test function while power on, which is convenient for the customer to test. The GS8206 provides SOP8 packaging, working environment is from -40 °C to + 85 °C.
