DESCRIPTION
HL1606 is a LED driver IC with SPI controlled. We can get “complex mode changes” by fewer data.
FEATURES
NMOS output
SPI controlled，plus synchronization speed control port: S-I
PWM output,frequency:500Hz
With a internal “change model” unit，only data calls, reducing the amount of data.
Speed control bit，can speed up “changes in a pixel” rate of 2 times.
Latch enable bit，concatenated string at a point can be read or not read data.
Built-6 road, drive two pixels（three-output get a pixel）

then input ”0” to the end is okay(red to yellow gradually). Clock signal has been sent to CK_I, sent a “1” to L_I
after 8 clock signal. Change once the signal of S_I, the output series change once. A clock cycle in S_I,.
output is keep in 512Hz refresh frequency, to maintain the same level(series) of output duty cycle refresh. If
no data sent to S_I, output will remain the same duty cycle refresh. Just finished in a color change, change
the data of D-I.

Application Notes
1. Picture(1),1st connection method: triode will not connect to output of IC, output current reach 30Ma,output
can connect to two-ways, ensure that the output voltage must be less than 6V.
2. Picture(2), 2nd connection method: triode connect to output of IC. Because the NPN-type transistor at the
base took on the extreme pull-up resistor, the “output duty cycle of IC” and the” LED brightness” is
inversely proportional to. When the IC doesn’t output, the transistor fully conducting, LED full-bright.
