Abstract
A electronic device includes an electrical component powered by a battery and a compartment to receive the battery. A low voltage cutoff circuit is configured to couple to the battery. The low voltage cutoff circuit includes a switching device having a control terminal, a current sourcing terminal and current sinking terminal and a resistor coupled between the control terminal and a first terminal of a battery. The circuit has first and second output terminals. The first output terminal is coupled to the first terminal of the battery and the second output terminal is coupled to the current sourcing terminal of the transistor. The first and second output terminals are configured to accept connections to positive and negative terminals of the electrical component.
