TPL5110: Permanently On

Part Number: TPL5110

Hi,

Good day.

Our customer would like to know if it is possible to switch on the TPL5110 permanently with a pushbutton during operation?

Here's more detail of his application:

I want to wake up a microcontroller in a certain interval, so that it transmits sensor values via Bluetooth during the waking phase and then goes back to sleep. I know that the microcontroller applies a signal from low to high to the done pin of the TPL5110 so that it disconnects the microcontroller from the power.

All this is already working.

I need to power up the microcontroller manual for a longer period of time so I can assign a name to the MCU via Bluetooth.

There is the manual mosfet power on with spst switch (see attachment). I have also provided this in my schematic.

My question is if it is possible to switch on the MCU for a longer interval than the set delay time interval. If yes, then I would like to know how.

Is it enough to keep the SPST button pressed permanently?


Looking forward to your inputs. Thank you.


Regards,

Cedrick
