Part Number: TLC5944 Other Parts Discussed in Thread: LP5864 , TUSB3410 Hello,
I have a specific requirement to drive a LED array consisting of 60 LEDs, with 30 IR LEDs and 30 RED LEDs. After researching the capabilities of the TLC5944, I believe that…
Part Number: TLC5944 Hi team,
Can you have a look at the following customer question, please?
In the section "Internal Pre-Charge FET" of the data sheet it is stated that the pin "VUP" (Pre-charge FET power supply) has to be connected with the supply…
Part Number: TLC5944 Hello,
I would like to know how to handle unused output pins of TLC5944.
There is a related thread already and it says "for unused output pins, pull them down to the GND" .
But isn't it detected by the LOD and generate XERR…
Part Number: TLC5944 Other Parts Discussed in Thread: TLC59461 , TLC5945 Hi, I'd like some input on how to read the supply current specs for the TLC5944 led driver.
Can I assume that Icc3/Icc4 in the datasheet (picture below) is without any LED…
Part Number: TLC5944 Hi, I'd like some input on how to read the supply current specs for the TLC5944 led driver.
Can I assume that Icc3/Icc4 in the datasheet (picture below) is without any LED's "on"?
Why does Typ/Max increase together…
Hello Kenneth,
After long time we made test in thermal chamber within current up to 70ma. It seemed that thermal event did not appear. I think that is appropriate layout with a lot of polygon and heatspreader. After counting power dissipation everything…
Other Parts Discussed in Thread: TLC5944 Hi! I am using TLC5944 in a multiplexed back lighting solution and I am running all the LEDs off a LiIon battery. I have noticed that some leds only shine for a short period of time and I have verified that this…
Hi, Could you tell me about GS and DC shift register DCSEL changeing timing? Data sheet has the following description in page19 and 20. '' A DCSEL level change is allowed when SCLK is low and 100 ns after the rising edge of XLAT.'' My customers…
Other Parts Discussed in Thread: TLC5944 Hi, Could you tell me about TLC5944 terminal processing? How should the unused output pin process it? And, Is the data output may be 0 (000000b)? I will listed below the use conditions of the customer. ・Customers use…
Other Parts Discussed in Thread: TLC5944 Hi, Could you tell me about TLC5944 SOUT pin? Please tell me the following register value. Customers want to know its value for circuit design. Best Regards, Yusuke/Japan Disty
