HL1606 DESCRIPTION
HL1606 is a LED driver IC with SPI controlled. We can get “complex mode changes” by fewer data.
HL1606 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˅

Description of HL1606 build-in module
Fadein module˖
When a data bit is 10(D2D1 or D4D3 or D6D5) and the latch is enable, corresponding output state of LED is fadein. After get the brightest state, it will keep the state, until the new data input by effective latch.
Fadeout module˖
When a data bit is 11(D2D1 or D4D3 or D6D5) and the latch is enable, corresponding output state of LED is fadeout. After the lights out, it will keep the state, until the new data input by effective latch.
T Cycle time of change–T˖
When D7=0,T=Tzc×128 set ,series is 128. For example: When Zc=50Hz,T=2.56s,if every latch
is effective, fadein/fadeout module will resume the change.

Impression Drawing & Data Format
Monochrome , one-way, gradually run
Description: There is a “gradual change” mode in HL1606, so D_I only need one set of data”10110000”, then input ”0” to the end is okay. 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 decline in a series. 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.
Colorful fluttering
Description: There is a “gradual change” mode in HL1606, so D_I only need one set of data”10001011”, then input ”0” to the end is okay(red to green 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.
Full-color fluttering
Description: There is a “gradual change” mode in HL1606, so D_I only need one set of data”10001001”, 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.
HL1606 Application
Application Notes
- 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.
- 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.
- Picture (3), internal structure of the “output port of IC”. The output is NMOS open-drain output.
- Picture (4), application drawing of cascade. Connection method of output termination (U1-UN) is same. Ceramic capacitor ”※” should be as close as possible to the chip, and work before the power input to the IC. Resistance “#” is adjustable, adjust the brightness of LED by adjust the value of resistance, and then we can get different blending effect. When the IC work, first into the highest, then into the low, the output is after the drive of “chip control signal”, this output can be used as the input signal of back-end circuit.
