Abstract:
A reactivation circuit coupled with a system having a protection mechanism which prevents runaway current, the reactivation circuit comprising:a charging circuit coupled with a storage element, the charging circuit configured to supply a charging a current to the storage element, once the protection mechanism is activated to prevent the supplying of the output current; a monitoring circuit coupled with the system, the storage element, and the charging circuit, the monitoring circuit configured to monitor the voltage across the storage element and to signal the system when voltage across the storage element exceeds a predefined threshold and further configured to deactivate the charging circuit when the voltage across the storage element exceeds the predefined threshold; and a latch coupled between the monitoring circuit and both the charging circuit and the system, configured to receive a signal from the monitoring circuit, the latch further configured to maintain the charging circuit in at least a deactivated state as signaled by the monitoring circuit.
