[0003] However, when using this type of power management chip to design a device or device that does not need to be triggered by a button, the button trigger signal becomes a restrictive factor in the design. If the power management chip is replaced, the design of the power supply of the entire system is tantamount to overthrowing and starting over.

Abstract

The invention discloses a system automatic power-on circuit and method. The circuit comprises a constant power generation unit, a pulse generation unit, a power supply management unit and a system CPU unit, wherein the input end of the constant power generation unit is connected with a power supply, the output end of the constant power generation unit is respectively connected with the pulse generation unit and the power supply management unit to supply power for the pulse generation unit and the power supply management unit; the pulse output end of the pulse generation unit is connected with the pulse input end of the power supply management unit; the output end of the power supply management unit is connected with the input end of the system CPU unit. The system automatic power-on circuit and method disclosed by the invention have the advantages that the circuit structure is simple, the cost is low, the pulses generated by the pulse generation unit are used for triggering a power supply management chip to realize the automatic power-on of the system, the stability is good, the compatibility is good, the development period is short and the circuit and method are suitable for various constant power supply devices.

Description

Technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a system power-on automatic startup circuit and a startup method thereof. Background technique [0002] In current electronic devices, especially handheld (consumer) electronic devices such as mobile phones and tablet computers, the booting of the device is usually started by pressing a button on the device to generate a pulse signal. In order to facilitate the design, the corresponding power management chip regards the triggering of the key pulse as a necessary condition for powering on the system. [0003] However, when using this type of power management chip to design a device or device that does not need to be triggered by a button, the button trigger signal becomes a restrictive factor in the design. If the power management chip is replaced, the design of the power supply of the entire system is equal to an overthrow. Cause a relatively large design risk and affect t...
