Assignee: MONOLITHIC POWER SYSTEMS, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A fault reporting structure of an integrated circuit having at least one power MOSFET, wherein the at least one power MOSFET has a plurality of MOSFET cells with each MOSFET cell having a drain metal and a source metal, wherein the integrated circuit has a power MOSFET area for routing the drain metals and the source metals of the plurality of MOSFET cells, the fault reporting structure comprising:
a metal net routed in the power MOSFET area or in an area above or below the power MOSFET area; and
a fault reporting pin coupled to the metal net and configured to provide a fault signal indicating whether the integrated circuit is in a normal status or in a fault status.
