Hum thank you
I thought it would be possible to connect all my super cap together auto balanced and get a big tank of energy.
Like small rivers which drop in a big lac :)
But you are right, one big capa should be more optimized.
Wow, now I'm completly confused.
Here is the right schematic:
"Without any gate driven low the uC gets it´s power via the mosfet internal body diodes. There will be about 0.55V of voltage drop.
Adding schottky diodes in parallel to the internal body diodes may reduce the voltage drop. "
So...
Thank you very much
I have some difficulties to imagine the schematic:
How the gate changes his states low to high?
Do you have any schematic?
Thanks for the link,
my low power µC needs few mA (<5mA) and inLow-power mode:
❐ Deep Sleep: 1.3 µA with watch crystal oscillator (WCO) on
❐...
The things is I want to power supply a low power microcontroler with the energy available so put another circuit which consums current to select the highest voltage seems too much...
Hi everyone,
I am wondering how I can manage with different voltages from different super cap.
I explain the schematic below, I have 4 supercap (400mF rated 3.3v) that are charged by different controlers from generators. This means that at a time T1s the C1 could provide maybe 3.24V if it is...
Ok, I find the way to do it:
Design->Netlist->Update free primitive
And the error disappears.
I don't really understand If i did it correctly, what was the problem and what "Update free primitive" does...
Hi everyone,
I'm doing a footprint of a USB connector like this:
As you can see there is a Land NO.3 which is supposed to be conected to gnd I guess. To do this, I use Snap points and use a solid region (Place->Solid region)
My problem is I can't assign a designator like a pin. So I tried to...
Hi everyone,
I'm using a Capsense from PSoC which is use a Sigma Delta Modulator to measure a capacitance.
First of all they assume that the capacitance is equivalent to a resistor with switch sw1 and sw2:
After that we have:
I don't understand how they find:
Ic= Cs Fs Vcmod
Ic is the...
