Filed: 2000-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a power source voltage monitoring circuit which dispenses with a fixed voltage circuit as a reference value and is able to monitor power source voltage down to low voltage. SOLUTION: This invention is provided with divided voltage means D1, R1, R2, a comparator CMP which inputs divided voltage VCX and zero voltage GND compares both voltages, and output transistor means Q1, Q2, Q3 which output monitoring signals at an output terminal through the comparator's output. The comparator compares offset voltage VOS which is acquired from the area ratio with the divided voltage VCX. The comparator's power source voltage can be lowered down to around 1 V and the voltage area can be monitored by setting up the threshold voltage which monitor power source voltage as around 1 V.  By setting up values for divided voltage resistors R1, R2 equalized to the partial differential of temperature between the forward voltage of diode D1 and the offset voltage of the comparator CMP, the temperature characteristic of the threshold voltage VTH can be set off and the stable monitoring of power source voltage regardless of the changes in temperature is enabled.
