TPL5010: Using a longer timeperiod than specified by the datasheet

Thomas Nielsen36

Part Number: TPL5010


Hi

I would like to know the possibilities of using the TPL5010 for a time period of 24Hr instead of the 2Hr specified by the datasheet. I have calculated the resistance to be 542kOhm. What would happen if I were to use the calculated resistance? Is it possible? 

Are there other solutions in your product catalogue that will achieve the same while using the same amount of power?

    Dear Thomas,

    Thank you for your interest in this device.

    I do not have a detailed description of the timer functionality so I can not calculate what will happen outside the specified range. I suspect you will be able to get longer delay than 2hr but not to 24hr (12x) I think. You can see there are 1650 step to get to 2hr so likely the counter can get to 2047 (2^11-1)...

    I do not see other device with a longer time delay.

    Regards, Simon.
