Hi Nathalie,
I went into lab to try to replicate this. I used the TPL5010EVM. I have attached the oscilloscope capture below.
As you can tell, I am manually issuing several DONE pulses (purple waveform) to the device during each interval, but the…
Hi Jason,
Can you send me your oscilloscope capture of the WAKE, RSTn, and DONE waveforms? This may shed some light into what is causing the WAKE pulses.
In my setup I am using the TPL5010EVM powered by a coin cell battery and DONE is pulled to…
Hi Nizar,
I wasn't able to replicate your issue on my bench using TPL5010EVM. In my setup:
VDD = 5V
R_ext = 500ohm => T_ip = 100ms
DONE pin is pulled down to ground
With this setup, RSTn will be periodic; RSTn will remain high for 100ms…
Hi Henry,
I tested this on the TPL5010EVM with CR2032 battery. If VDD is connected to DELAY/M_RST indefinitely, RSTn will be pulled to GND indefinitely.
Also, it is not recommended to pull DELAY/M_RST to VDD during startup. After POR, the device…
Hi Hong,
Thanks for providing your oscilloscope waveforms. They are very helpful for me because I still am not able to replicate your issue.
Can you confirm that you are testing on the TPL5010EVM? Or are you using another board?
Q5: Can you give…
Dear Lane,
Thank you for your reply.
My test bench is attached.
I used two current sources to supply 300uA to two 47uF capacitors and limited the voltages of current sources to be 2.1V and 2.9V seperately.
So the two 47uF can be regarded as two…
