Title:
半導体装置
Document Type and Number:
Japanese Patent JP4094984
Kind Code:
B2
Abstract:
An HNMOS transistor ( 4 ) has its drain electrode connected to the gate electrode of an NMOS transistor ( 21 ), and a logic circuit voltage (VCC) is applied to the drain electrode of the NMOS transistor ( 21 ) through a resistor ( 32 ). A ground potential is applied to the source electrode of the NMOS transistor ( 21 ). A drain potential (V 2 ) at the NMOS transistor ( 21 ) is monitored by an interface circuit ( 1 ), for indirectly monitoring a potential (VS). Thus provided is a high voltage integrated circuit for preventing damage to a semiconductor device used for performing bridge rectification of a power line.
