Protection circuit with a FET device coupled from a protected bus to ground
Last updated:
Abstract:
A semiconductor device includes a voltage input circuit node and a ground voltage node. A first transistor is coupled between the voltage input circuit node and the ground voltage node. A triggering circuit is coupled between the voltage input circuit node and the ground voltage node in parallel with the first transistor. The triggering circuit includes a trigger diode. An output of the triggering circuit is coupled to a control terminal of the first transistor. A load is powered by coupling the load between the voltage input circuit node and the ground voltage node.
