Abstract
Disclosed herein is method for fault detection and communication in analog power electronic circuits with a multiplicity of electronic fuses (e.g., a primary fuse and at least one secondary fuse). Current flow is monitored through each fuse. Fault conditions in these electronic fuses are identified. Upon detection, the fault signaling line, which is common to all fuses, is driven to a voltage indicative of the detected fault condition. The primary electronic fuse then latches the voltage on this fault signaling line. A detection and communication circuit enables corrective actions to be performed at the fuse level, dictated by the latched voltage.
