Abstract
According to embodiments of the present invention, a flameless candle circuit includes an application-specific integrated circuit (“ASIC”) having a first power terminal, a second power terminal, and an output. The circuit also includes a light-emitting diode (“LED”) and a single-pole switch. The LED is configured to receive a signal from the output of the ASIC. The single-pole switch is configured to selectively provide the battery voltage to at least one of the first power terminal and the second power terminal. Additionally, the single-pole switch is configured to remove the battery voltage from both of the first power terminal and the second power terminal to turn the ASIC off. The ASIC is configured to drive the LED in a first mode when the battery voltage is provided to the first power terminal. The ASIC is also configured to drive the LED in a second mode when the battery voltage is provided to the second power terminal.
