    Abstract: An infrared circuit for a single battery and a remote controller using the same are provided. The single battery outputs a battery voltage. The infrared circuit comprises an IR LED circuit, an inductor and a microcontroller. The IR LED circuit is coupled between the battery voltage and a common voltage. The inductor is coupled between the battery voltage and the common voltage. The microcontroller has an I/O port coupled to the inductor and the IR LED circuit. When infrared rays are emitted, the microcontroller controls the battery voltage to charge the inductor through the I/O port, and a continuous current of the inductor forces the IR LED circuit to turn on.

    Abstract: A method for power-on sequence and a device with a low current power source are provided in the present invention. The method is used for enabling a device including a low current power source, a first circuit module and a second circuit module, wherein the low current power source is used for providing a power voltage. The method includes: switching a low voltage reset signal from a first logic voltage to a second logic voltage when the power voltage rise to a threshold voltage; enabling the first circuit module after a first preset time from the time when the low voltage reset signal switches from the first logic voltage to the second logic voltage; and enabling the second circuit module after a second preset time from the time when the first circuit module is enabled.
