ABSTRACT:
A branch protection circuit is provided to isolate a power network from a faulty load such as an overcurrent condition. The circuit employs a current-sense field effect transistor formed from two power field effect transistors integrated onto the same silicon substrate. The current-sense-FET is provided to detect if the electrical current in the larger FET has exceeded a predetermined threshold level. The circuit does not measure the specific current flowing through the transistors, and the circuitry employed to detect if the threshold current level is exceeded is significantly less complex than circuitry otherwise required to determine a specific current flow through one of the transistors.
