High current value even in sleep mode
Posted byJin-Hoon Kim60 points 1 replyHi Dialog,
I am using DA14531 and one weird ting I found out was that even I make the device to extended or deep sleep mode, the current was about ~3 mA, still much higher than the reference value. Similar value was recorded when I used a multimeter to measure the current value.
Is there any suggestions that I can do to reduce the current?
I attached a screen shot of SmartSnippets window during current measurement.
Thank you!

Hi Jin-Hoon Kim,
Thanks for your question online. Is it a custom board, or you are using any of our DKs?
If you are using the Pro-DK, did you calibrate it? Check section 12.10. Calibration Procedure :https://s3.eu-west-2.amazonaws.com/lpccs-docs.dialog-semiconductor.com/UM-B-083/power_profiler/powerProfiler.html
Please share the jumper configuration of the Pro-DK.
Does the DA14531 boot from System-RAM or SPI Flash? If it boots from System-RAM, make sure that the debugger is de-attached?
Which SDK example are you using?
Could you follow the Sleep mode tutorial and check if you can replicate it?
