Abstract
A reset ramp control structure and method is described. A fast ramp down condition of a monitored voltage is detected and used to force the state of system reset. Delay between fast ramp detection and the forcing of system reset is adjustable. Operation is adaptable to include all DC power systems. The reset ramp control structure provides operational protection during fast ramp down conditions when standard reset circuitry may not be operational.
