Abstract

The embodiment of the invention discloses a power management circuit. The power management circuit solves the technical problem that at present, because a battery of equipment is mostly wasted in the idle or standby process, serious loss of the battery is caused. The power management circuit comprises a power input end Vin, a power output end Vout, a resistor R1, a resistor R2, a resistor R3, a capacitor C2 and an MCU control end. A semiconductor device comprises a first connecting end, a second connecting end and a third connecting end. The first connecting end is connected with the power input end Vin, the second connecting end is connected with the power output end Vout and one end of the resistor R2, the other end of the resistor R2 is connected with one end of the resistor R3, the first connecting end is further connected with one end of the resistor R1, the other end of the resistor R1 is connected between the resistor R2 and the resistor R3, the other end of the resistor R3 is connected with one end of the capacitor C2, and the other end of the capacitor C2 is connected with the MCU control end.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a power management circuit. Background technique [0002] The continuous improvement of global energy-saving demand, the continuous advancement of digital technology, the increasing number of split power supply structures and the requirement that electronic equipment must comply with mandatory energy efficiency regulations, together with the development trend of miniaturization and multi-function of portable devices are the driving force behind the development of power management technology , power management refers to how to efficiently distribute power to the different components of the system. Power management is critical for mobile devices that rely on battery power. A good power management system can double or triple battery life by reducing power consumption when components are idle, so power management circuitry is one of the most straightforward and simple wa...
