TLC59116F: Maximum allowable reset pin rise and fall times

Part Number: TLC59116F


What is the maximum allowable RESET pin (#24 in the RHB package) rise and fall times?  We would like to connect an RS network to the reset pin.

By the way, is there a search function specifically for the LED Driver Forum?

Thank you for your time and help.

    David,

    Could you refer the RESET the datasheet page 8 for the detail spec?

    Yes, you can put the RC in the RESET PIN.

    Any more question please let me know, thanks!

    Thank for you for replying so quickly about whether or not we can put an RC network on the RESET pin.

    Regarding:
    >> Could you refer the RESET the datasheet page 8 for the detail spec?

    I looked at page 8 and can not find any reference to RESET. I hate to assume there's some kind of a reference on page 8 to RESET when it isn't explicit.

    What I was hoping to see in the TLC59116F datasheet was mention that the RESET pin has a Schmidt triggered input or some kind input hysteresis specification. Or some kind of input maximum allowable rise and fall time specification.

    Thank you again for your time and help.

    Hi Dave,
    Sorry for the typo error, it is page 6, you can see the requirement is 10 ns pulse , any more question please let me know, thanks!

    Thanks for clarifying. We will have no problems meeting the 10nSec minimum RESET pulse width. Because we are using an RC network on the RESET pin, the rise and fall times on the RESET pin will be 10 to 20 µSec - that's the concern. (Per your answer above, 10 to 20 µSec rise & fall times on the RESET pin is not a concern.)

    I'll check tomorrow to see if you have any other comments. At that time I'll click the "This resolved my issue". Thanks for your help, we definitely appreciate it.
