Claim 3:
4. The apparatus of claim 2 further comprising:
a first terminal for receiving a first positive battery voltage;
a second terminal for receiving a second positive battery voltage that is substantially equal to the first positive battery voltage;
first and second diodes comprising first and second anodes, respectively, and first and second cathodes, respectively;
wherein the first and second anodes are connected to the first and second terminals, respectively;
wherein the first and second cathodes are connected together to provide a common voltage that depends on the first or second positive battery voltages;
wherein the second voltage regulator is configured to convert the common voltage into the second supply voltage for the high voltage stage;
wherein the voltage regulator is configured to convert the common voltage, or another voltage that is dependent on the common voltage, into the supply voltage for the microcontroller.
