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
Hi Cedrick,
keeping Delay/M_DRV High will reset the timers. As soon as the pin goes low again the timer starts and the device is back in normal mode.
The time for DRV go high again is t_DB + t_IP.
