Title: Excess voltage protection circuit provided with excess voltage removing and detecting function
Inventor: DAVID P MORRILL
IPC: H03K17/08
Filed: 2001-02-13
Abstract: PROBLEM TO BE SOLVED: To provide a protection circuit which detects an excess voltage condition giving influence to currents flowing through a pull up transistor and turning off the pull-up transistor. SOLUTION: While the excess voltage condition exists in a common bus (20), an excess voltage protection circuit (30) blocks currents flowing through a high potential supplying rail via the pull-up transistor of an output circuit. The protection circuit has a first protection branch (60) to be supplied with power through the high potential supply rail of the output circuit which has to be controlled and protected by the potential in a bus and a second protection branch (70) to be controlled by the high potential supply rail and supplied with power by the potential on the bus. When the excess voltage condition is generated, the second branch is energized to regulate the output from the first protection branch.  When the excess voltage condition is removed, the output stage of the first protection branch is changed immediately to maintain the operating condition of the pull-up transistor equal to the state before the excess voltage condition.
