Other Parts Discussed in Thread: TLC59281 Hello @TI,
Although we recognize that the TLC5928x ICs are designed for driving LEDs, although they could be a nice a compact way to drive small signal relays with a low constant current. For example the Omron…
Other Parts Discussed in Thread: TLC59283 Hi all,
I'm designing a RGB LED Screen with TLC59283 and I've seen on the datasheet that in the configuration normally is used a Resistor+ zener diode (as a protection I can imagine).
In my design the…
Hi Kazuya,
Yes this control method should be OK and I do not have other concern.
But I wonder why customer choose TLC5948 for such usage. we have some simply 16-channel on/off device like TLC59283 or TLC5929.
Hi all,
when we want to have a zener as voltage regulator we normally use this configuration:
Why in this case do you use a resistor in series with the zener? I can't see very clearly how does your configuration work? Can you show me an exaple? …
Hi John,
it is not necessary to change the resistor in some situation.
you just need to calculate the Iout when using the same resistor and check whether it can meet the device's request. Below pictures shows the details how to calculate the channel…
Part Number: TLC59116 Other Parts Discussed in Thread: TLC5940 , TLC59283 Hi, support team
My customer has the questions as follow:
Is there alternate part for TLC59116IRHBR?
Thanks so much.
Best regards, Yuki
Hi Chandana,
Here is a sample code for TLC59283, which have the same interface with TLC59281. If you series multiple daisy-chained ICs, LAT signal is used to select the right data load into related IC and BLANK signal is used to synchronize all ICs display…
Thank you Charles. From what I can discern so far (but please correct me if I’m wrong here, which is quite possible!), Figs 12/13 of the application note you cited seems to suggest that time multiplexing, to control more than 16 LEDs using a single TLC59283…
Hi A,
1) Yes, there is no R/G/B difference from the device point of view. we have one TI reference design with TLC5958 that you have already found in last E2E question.
2) Yes, for 8*32, 2* TLC6946 with 8 scan lines is enough. they are similar for you…
