Hello everyone!
I am using the Step-Up voltage Regulator U1V11F3 in my Energy harvesting project.
the aim of the project is to transmit data wirelessly from a Thermoelectric generator (TEG) mounted on a rocket nuzzle to a host computer using the Embedded device (EZ430-RF2500) from Texas Instrument.
I am using the Step-Up voltage Regulator U1V11F3 to step-up voltage in the range (0.5V - 1V) coming from the TEG to a voltage of 3.3V so as to be able to power the Embedded device.
But it turns out that the control line of the U1V11F3 requires a rising edge for it to fire up, it doesn’t just start up with a supply voltage of 0.5V. I observed this by supplying 0.5V using DC-Power Generator and every time i have to on and off the DC-Power Generator before the U1V11F3 fires up.
I have thought of using a Schmitt trigger, but it didn’t work.
Any advice on how to go about this issue? because when carrying out the project in the field i have no control over the voltage supply, in fact i will not be present in the field for safety reasons. so i need something that will create like a rising edge to the U1V11F3.
That was my observation, so please if you could suggest some external circuit that can be used to resolve this i would really appreciate it
Thank you!
