Title: The Innovative Contributions of Robin Shields
Introduction
Robin Shields is a notable inventor based in Inverclyde, GB. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and safety of electronic devices through innovative circuit designs.
Latest Patents
One of Robin Shields' latest patents is an over-current protection circuit. This regulator system includes a power device and a sense device. During normal operation, the power device delivers current to a load while the sense device monitors the load current. An over-current mode is activated when the sensed load current exceeds a short-circuit current limit. In this mode, the power device is switched off to minimize energy loss. Once the short-circuit condition is resolved, the system returns to normal operation. The design ensures that the quiescent current does not increase with load current, and the short-circuit current limit decreases automatically with rising operating temperatures. This innovation significantly reduces energy losses and minimizes the risk of thermal-induced device failures during short-circuit conditions.
Another important patent by Shields is a protection circuit for deactivating a transistor during operation. This circuit is designed for a semiconductor switch that controls a load. It utilizes control circuitry to switch the semiconductor on in response to a signal and off in response to a deactivation signal. An overvoltage detector circuit generates an overvoltage signal when the output voltage exceeds a predetermined value. The circuit includes a Zener diode and multiple transistors that work together to ensure the safe operation of the semiconductor switch.
