Abstract
An ignition isolating interrupt control circuit ( ) includes a main transition circuit ( ) isolating a first activation circuit ( ) from an ignition circuit ( ). The main transition circuit ( ) includes a source terminal ( ) that is electrically coupled to and receives a first source power from the first activation circuit ( ). An input terminal ( ) is electrically coupled to a second activation circuit ( ) and receives an activation signal. An output terminal ( ) is electrically coupled to the ignition circuit ( ) and receives and supplies the first source power to the ignition circuit ( ) in response to the activation signal. A power source monitor cutoff circuit ( ) including a comparator is electrically coupled to the first activation circuit ( ) and to the ignition circuit ( ) and disables the ignition circuit ( ) when a source voltage level is less than a predetermined voltage level.
