Abstract
A system for and of charging a capacitor can be used in a failsafe device. A voltage level is sensed at the capacitor, and a current is provided to the capacitor until a threshold voltage level is reached. The threshold voltage level is above a target voltage. The target voltage is a voltage level associated with enough energy being stored for a failsafe operation.
