ABSTRACT:
An integrated power device comprises a power transistor (26) and a plurality of sense transistors (38), (40), (42), (44), and (46). Sense transistors (38), (40), (42), and (44) are constructed around the periphery of the active area occupied by power transistor (26). Sense transistor (46) is located within the interior of the active area occupied by power transistor (26) and contact is made to the necessary source region (64) of transistor (46) using a second level of metal interconnect to form a source contact (74).
