"textContent": "A control circuit and method are disclosed for controlling a contactor in a motor vehicle. The control circuit includes a driver circuit having an output to couple to a control terminal of a contactor, the driver circuit having a supply input and a control input. A Boolean logic gate has an input coupled to a safety disable control signal, a second input and an output coupled to the control input of the driver circuit. A hold circuit has a first input coupled a loss of propulsion signal, a second input coupled to an pulse width modulation (PWM) control signal and an output coupled to the second input of the Boolean logic gate. Based upon the output of the loss of propulsion detection circuit, the output of the output latch circuit is either maintained at a prior Boolean logic state of the output of the output latch circuit or is based on the PWM control signal.",
