Hi Team,
Using TLC59284DBQ, ESD testing has issues, Air discharge (8KV) or contact discharge (4KV) LED driver chips may occasionally experience reset phenomena, and the chip's external power supply cannot solve…
Part Number: TLC59284 Good day,
I am running 20x tlc59284's in series. The CLK and Latch pins are all connected - Total CLK track length about 1450mm. The Data pin runs from one to the next between the SDI and SDO pins.
I have added a 74HC14 after…
Part Number: TLC59284 Other Parts Discussed in Thread: TLC5926 Dear Sir/Madam,
TLC59284 has a max 35 mA output current for each channel. We have an application in which we activate only one of the output at a time around 1 ms duration and scan each…
Hi,
It means every channel has the current sink capability for 35mA max if Vcc < 3.6V.
If you are looking for a 90mA device, please check TLC5926. It supports 120mA max current for each channel.
If you think this answers your question, please…
Part Number: TLC59284 Other Parts Discussed in Thread: TLC5944 , Hi,
I can see the resistor on SOUT in simplified diagram, so I think this is output resistance of SOUT. Can I know the typical value of this resistance?
Best Regards,
Satoshi / Japan…
Part Number: TLC59284 Hello Team,
I'm working with an engineer that had an interesting question on how to dim their 16-segment LED with the TLC59284 without using external circuitry.
While the current is typically set by using an external resistor…
Hi Kenneth,
Thank you for your response. Your comment will be enough for customer. I understand that this +/- 3%(max) include the channel-to-channel variation and also Iout_set variation.
Best Regards,
Satoshi
Part Number: TLC59284 Hi,
Please let me ask if there is any limitation for rise and fall time of input digital signal. My customer consider to use slow rise and fall time to reduce high frequency EMI noise and signal reflection. From the datasheet,…
Part Number: TLC59284
Hi,
my customer would like to turn on and off 5 LEDs at 500kHz frequency. No brightness control is needed.
In the datasheet, it only specify the data transfer rate to be 35MHz.
My understanding is that the switching frequency…
