ABSTRACT:
A battery status indication circuit and a method of indicating battery status. The battery status indication circuit comprises: (1) an indicator having an inactive state and an active state and (2) an indicator modulation circuit adapted to receive a charge level signal indicating a charge level of a battery and transmit, in response thereto, a pulsewidth modulated indicator signal to the indicator, a duty cycle of the indicator signal being a function of the charge level, the indicator thereby toggling between the inactive and active states to provide an indication of the charge level. A single indicator having only two states can therefore be employed to indicate multiple grades of battery charge level.
