PROTECTIVE DEVICE OF INTEGRATED POWER STEP USING A PLURALITYOF BONDING WIRES TO CURRENT LOAD OF PACKAGE

摘要

PURPOSE: To provide a voltage regulator which can detect ruptures of bonding wires for connecting a pad and a lead at the final test of a final product, i.e., an integrated circuit. CONSTITUTION: A voltage regulator includes a connection path having resistors (Ra and Rb) lower than resistors (R1 and R2) constituting a sense voltage divider between pads at least by a factor of two figures.
