ABSTRACT:
A low voltage control circuit, and associated method, is provided for maintaining at least one output terminal in a known state regardless of the state of the inputs, when at least one voltage to be monitored is above a threshold voltage and below a predetermined limit voltage, comprising control means for providing a deactivating output voltage when the voltage to be monitored is below the predetermined limit voltage, output means electrically coupled to the control means for receiving the output voltage from the control means and for receiving at least one input voltage, the output means being deactivated in response to the deactivating output voltage to provide a known voltage state at the output terminal until the voltage to be monitored reaches the predetermined limit voltage whereupon the control means will provide an activating output voltage to the output means to enable the voltage state at the output terminal to be controlled by the state of the inputs.
