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.
