    摘要: A power supply source selection circuit is provided with a comparator and a switch. The comparator has an input to accept a first reference voltage directly proportional to a bandgap reference voltage. For example, the bandgap voltage may be derived from a battery voltage. The comparator has an input to accept a second reference voltage directly proportional to a first supply voltage (e.g., a line voltage), and an output to supply a switch signal in response to comparing the second reference voltage to the first reference voltage. The switch has an input to accept the first supply voltage, an input to accept a second supply voltage, and input to accept the switch signal. The switch has an output to supply a third supply voltage to a regulator. The third voltage has a voltage potential less than or equal to a maximum voltage value. The switch selects between the first supply voltage and the second supply voltage in response to the switch signal.
