Abstract
A low voltage protection which prevents an associated circuit from generating erroneous signals during power-up, power-down or power failure conditions. A voltage comparison circuit, powered by a first power supply, detects low voltage conditions in a second power supply and causes a switching circuit to inhibit control and power signals of the associated circuit.
