    Relay switch to detect power source

    I tried to find a Crude voltage boost circuit but could not come up with that. Also i am wondering what do you mean by use a common power supply. the issue is, i have to use a USB to connect the device to the computer and the USB gives 5V. At the same time the system is running at 9V with a...

    Relay switch to detect power source

    I was thinking 3xAAA batteries too. But the requirement is to use a 9V alkaline battery.

    Relay switch to detect power source

    I am using a voltage regulator to drop 5V to 3.6V and a Flyback to drop 9v to 3.6V. So its not a common circuit for both.

    Relay switch to detect power source

    So what you are suggesting is to boost the 5V to 9V, so then there won't be a system damage and i don't need to use a relay switch?

    Relay switch to detect power source

    Yes, its a Low power device. The system runs at 3.6V. I had to drop 5V to 3.6V and 9V to 3.6V.

    Relay switch to detect power source

    9V is coming from the Battery and 5V from USB

    Relay switch to detect power source

    I need to find a switch that can detect whether it should go from 9v source or 5v Source. I am making a tool that has a battery power of 9v and it can also get powered from a USB device, which is 5V. If the customer need to connect the tool to a computer while its running from the battery...
