ACTIVE LIMITING CIRCUIT FOR INTRINSICALLY SAFE EQUIPMENT

An active limiting switch includes a comparator and a power switch. The comparator is configured to compare a reference voltage with a sense voltage. The sense voltage is representative of a proportional approximation to power in a load being driven by a battery. The power switch is configured to be...

Zusammenfassung:An active limiting switch includes a comparator and a power switch. The comparator is configured to compare a reference voltage with a sense voltage. The sense voltage is representative of a proportional approximation to power in a load being driven by a battery. The power switch is configured to be, in response to the reference voltage being less than the sense voltage, in an open state. The power switch is also configured to be, in response to the reference voltage being greater than the sense voltage, in a closed state creating a closed circuit between the battery and the load allowing the battery to provide a first amount of power to the load.
