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.
