Abstract
A control circuit for a protection circuit device includes first and second voltage boosters, a comparator coupled thereto, and a MOSFET for bypassing a direct current (DC) source. The control circuit may include a control logic circuit having a first input coupled to an output of the comparator, a second input receiving a disable command signal, a first output coupled to an enable input of the first voltage booster, and a second output, and a four terminal path inversion switch. The control circuit may include a supply voltage line, a sensor coupled to the second input of the control logic circuit, to generate the disable command signal, and to force the MOSFET into a conduction mode, and an external command terminal coupled to the second input of the control logic circuit, to receive the disable command signal, and to force the MOSFET into the conduction mode.
