Design a Low power Voltage supervisor circuit

I am seeking a skilled freelancer to design a compact and low-power circuit for monitoring and verifying the input voltage from a Laptop's USB 5V power supply. The circuit's primary function is to ensure that the incoming voltage falls within the specified range of 4.5V to 5.5V, with a target of around 5V Ideally. This monitoring is critical as the USB power will not only supply the circuitry for monitoring but also drive an adapter with a strict operating voltage range. It is essential to design the circuit with minimal power consumption to avoid overloading the USB, which has a maximum current supply of 0.5A. The freelancer should implement a solution that self-tests the adapter's input voltage each time it is utilized, providing a reliable indication of whether the voltage is within the required range. You can propose me what would be the output indication, a low power LCD monitor, A simple LED to represent the voltage is out of range or something more simple and reliable??? The design should be efficient, cost-effective, and compact, ensuring seamless integration into the overall system without the need for additional power sources.


If you possess expertise in low-power circuit design, USB interfacing, and self-testing mechanisms, we invite you to bid on this project. Please include relevant experience, proposed methodologies you will be using, and an estimated timeline for completion in your proposal. Additionally, demonstrate your understanding of the challenges associated with monitoring the USB power supply while ensuring minimal power consumption.

If you are an electrical engineer with the necessary skills and experience, I would love to hear from you. Please include examples of relevant projects you have worked on in your proposal.
