As the picture shows, this is a overvoltage detection circuit. It is applied to detect the overvoltage in any power supply circuit with a detection scale from 3 V to hundreds of voltage. Besides, it can also be used to lock detect the voltage which can detect 30μs transient overvoltage peak pulse. Under the common condition, the current consumption of this circuit will be under 25μA. So it is the best voltage control circuit in the battery power supply system. LTC1541 applied in this circuit is a kind of integrated circuit which contains a comparator A1 that has a small power compensation, operating amplifier A2 as well as UREF with the referred voltage of 1.20 V. This circuit demands a maximum of 13μA.
