Title: Semiconductor voltage detection circuit
Inventor: YAMADA YUSUKE
IPC: H03H7/24
Filed: 1989-06-01
Abstract: PURPOSE:To accurately detect a voltage to be compared by a method wherein individual voltage-dividing resistance parts are formed independently of each other via insulating islands and high-potential side ends of the voltage-dividing resistance parts are fixed to a potential of the corresponding insulating islands. CONSTITUTION:Individual voltage-dividing resistances 3, 4 are constituted of a plurality of voltage-dividing resistance parts 10 to 14 which have been connected in series; then, the individual voltage-dividing resistance parts 10 to 14 are formed independently of each other via insulating islands 81 to 85; high- potential side ends of the voltage-dividing resistance parts 10 to 14 are fixed to a potential of their corresponding insulating islands 81 to 85. Consequently, a change in a resistance value with reference to a voltage to be impressed is reduced; as a result, a gradient of the resistance value is not caused. Consequently, an accuracy of a resistance ratio decided physically by a length of a resistance is increased at the voltage-dividing resistances. Thereby, it is possible to accurately detect a voltage to be compared with reference to the resistance ratio.
