When the battery voltage is above the set point (typically 11V), the circuit is idle. With both switches in the normal position, the capacitor C1 charges up to the open circuit voltage of the diode tester. The TC54 series are CMOS voltage detectors that are especially well suited for battery-powered applications because of their extremely low 1 µA operating current and small surface-mount packaging. Configure time and date in Standard CMOS Setup to set the date and time in CMOS RAM.
