Error in the diagram I uploaded on this. I have uploaded the corrected one.Hii human people!!!
Here again with yet another potential solution for my power requirements.
I have decided to go for a more soft approach until it may be necessary to implement it in hardware. The latest approach will give the responsibility to the Micro controller.
The new approach involves using a basic resistor divider circuit to read the coin cell battery voltage using the Micro controllers ADC. When a voltage is read by the ADC, the MCU first switches OFF the transistor, then turns on the second boost converter through its enable pin.
This software routine will be user initiated when:
- User is provisioning a node as a "High Power Node" in the mesh network
- User would like to provide complementary power support for other use cases.
Perusing through several datasheets for boost converters, I observe the current consumption for the enable pins are usually in the microamps ranges (i believe I saw some in nanoamps region).
