Part Number: TLC5922 Hi there,
I have a TLC5922 and plan to operate it with an FPGA. I have been trying to set it up, but I haven't had any success and have a few questions:
Is the 'On/Off Register' set to low by default? I.e. from power on, to…
Part Number: TLC5922 Hello guys,
One of our customers evaluated TLC5922 for their new products and they got good results. So they'd like to adopt the device. But they have one concern. It is about data shifting in cascade of TLC5922. They want to know…

Other Parts Discussed in Thread: TLC5922 Hello,
Can an LED driver (such as the TLC5922) be used to drive constant currents through an array of resistors instead of LEDs? I was thinking that the 'Dot Correction' feature could be used to program the currents…
Hi Alex,
Thanks for explanation.
The way you use tlc5922 is putting channels always on, and adjust current amplitude by changing DC. In this way, there is no high speed turn on/off of channels, EMI performace should be no problem.

Hello,
I don't say this is the best solution but a device TLC5922 is a constant current driver with 7bit DAC. It has 16ch of 80mA outputs and these outputs can be paralleled (= 16x80 = 1.28A).
If this idea works, please check TLC59xx LED drivers with…
Hi, Takahiro-san,
I've answered your question in your formmer post:

For this original post, if you are looking for an I2C interface LED driver, TLC59116 has 16 channels and can support Vled up to 20V.
If SPI interface…
Hello Nicholas,
If SPI interface is acceptable, I would suggest TLC5922, a 16channel driver support 80mA max. It has 7bit DC for each channel, support 128 step LED current adjustment.
Thank you
Mike
