Title: Voltage monitor
Inventor: NEGORO OSAMU
IPC: G01R19/165
Filed: 1984-09-18
Abstract: PURPOSE:To detect a monitor voltage stepwise by a single comparator which uses a single detection voltage generating circuit, single switching element, and two light emitting diodes. CONSTITUTION:Resistances R1 and R2, the 1st light emitting diode LED1,the 2nd light emitting diode LED2, a diode D, a switching element SR, etc., are provided to constitute a voltage detecting circuit. When a voltage is applied between terminals P1 and P2 and its current flows through the resistances R1 and R2 to attain to a voltage gas threshold voltage value, the element SR turns on. Consequently, a resistance R3 and the diode LED1 illuminate, and the attainment of the monitor voltage to the 1st detection voltage value is detected. When the voltage further rises, the potential at a connection point (a) increases linearly and the terminal voltage across the element SR has a constant value, so the potential at a connection point (a) also rises to generate a potential difference between the connection points (a) and (b). When this potential difference exceeds the outward layer voltage of the diode D, a current flows through the circuit of the diode LED2 and diode D and the diode LED2 illuminates, thereby detecting the voltage attaining to the 2nd detection voltage value.
