Abstract
Transient overvoltage suppression circuit prevents voltage surges from damaging an attached load. The suppression circuit includes a transistor connected in series with a low-side or return line of the load. A control circuit monitors the voltage on the input line (i.e., high-side) and in response to a detected voltage transient turns the transistor OFF to isolate the load from the transient voltage.
