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.

@Agapaitanveermou

With my passion for circuit design and my team's specialized skills in electrical engineering, I believe that we are the perfect fit for your Low Power Voltage Supervisor Circuit project. Throughout our years of experience, we have refined our abilities to meet the unique challenges you have outlined in your project description. Our skills in USB interfacing and self-testing mechanisms will prove invaluable in ensuring your circuit adheres to the strict voltage range you specified, while incorporating a low-power consumption solution. In past projects, we've designed circuits for signal processing and power systems, as well as worked extensively with microcontrollers like Arduino. We know how important it is to provide accurate readings through an indication system which wouldn't further burden the USB system. As such, alongside other possible solutions for output indications (such as a low-power LCD monitor or simple LED), we can propose an even simpler yet efficient technique like generating an audio alert when there is any deviation from the desired range to ensure quick attention on potential issues.
