Patent JP-H0442063-A (JP)
Title: Voltage detecting circuit
Inventor: SHIBUYA YOSHIHIRO
IPC: G01R19/165
Filed: 1990-06-07
Abstract: PURPOSE:To make it possible to detect a plurality of voltages with one detecting circuit by connecting detecting parts in parallel in a voltage detecting circuit, and automatically switching the detecting parts. CONSTITUTION:A voltage across power-supply terinals B and C is slowly lowered. At first, an intermediate terminal H is recognized as ''high''. A transistor (Tr) T5 is turned ON, and a Tr T3 is turned OFF. An output terminal D outputs a voltage which is obtained by dividing the voltage across the terminals B and E with a resistor R3 and the Trs T4 and T5. When the voltage of the intermediate terminal exceeds the threshold value of the Tr R4, the Tr T4 becomes OFF, and the terminal D outputs the same potential as that of the terminal B. When the voltage of the terminal H is decreased to a value which is recognized as ''low'', the Tr T5 becomes OFF and the Tr T3 becomes On. The terminal D outputs a voltage which is obtained by dividing the voltage across the terminals B and C with the resistor R3 and the Trs T2 and T3. When the voltage across the terminals B and C is further lowered, the Tr T2 becomes OFF, and the terminal D outputs the same potential as that of the terminal B. When a detecting part 2 is automatically switched with a switching circuit 1 and the voltage is detected, a plurality of the voltages can be detected with the minimum circuit constitution.
