TPL5000

Other Parts Discussed in Thread: TPL5000

Hi All,

I want to use TPL5000 just as a timer without the supervisor and watchdog feature. I want a time delay of 32 s. How can I do that?

This is how I tried testing it out using an oscilloscope but it didn't work out.

pin 1 (D0) and pin 5 (GND) are connected to GND

pin 2-4 (D1, D2, VDD) and pin 10 (PGood) are connected to VDD 

pin 9 (RSTn) is connected to VDD through a 100k resistor

pin 6 (DONE) is connected to pin 7 (Tcal) and aren't connected to anything.

I check the output at pin 8 (wake).

The output at wake just looks like VDD. I checked, VDD and wake aren't shorted.

Thanks,

Muhammad

  • Hi Muhammad,

    I've contacted the applications support team for the TPL5000. Please expect a reply soon.

  • Hello,

    Has this issue been resolved? I am trying to use the TPL5000, but the WAKE signal never goes low regardless of what timing setting it is set to. I tried with D0,D1, and D2 set to VDD, but never saw the WAKE signal go high when PGOOD goes high. I also tried it with D0, D1, and D2 to GND, but still nothing.

    The power supply voltages and input are correct.
