Abstract

The invention discloses an energy management circuit for a sleep-wakeup mode and an energy management method. The circuit comprises a rectifier circuit of a power supply, a direct current booster circuit, a low dropout regulator and an electrical appliance. A super-capacitor, a timer circuit, a switch circuit and a reset circuit are arranged behind the rectifier circuit and the direct current booster circuit. The timer circuit controls sleep time of the electrical appliance (a chip). The switch circuit is taken as a power energy inflow enabling signal. The reset circuit is connected with a follow-up electrical appliance (the chip) and receives a work completion signal. A user can select specific sleep time according to a practical demand and the balance between power consumption reduction and normal work is achieved.

Description

technical field [0001] The invention relates to a power supply and an electrical appliance, in particular to an energy management circuit and an energy management method for a sleep-wake mode of an electrical appliance. Users can select a specific sleep time according to actual needs to achieve a balance between power saving and normal operation. Background technique [0002] The current mainstream chip energy management method is to process the power supply energy through simple rectification, boosting, etc., and obtain a relatively stable voltage through a low-dropout linear regulator for subsequent electrical appliances (chips). For example [Y.-J.Huang, T.-H.Tzeng, T.-W.Lin, C.-W.Huang, P.-W.Yen, P.-H.Kuo, C.-T. Lin, and S.-S.Lu, "A Self-Powered CMOS Reconfigurable Multi-Sensor SoC for Biomedical Applications," IEEE J. Solid-State Circuits, vol.49, no.4, pp.851–866, Apr.2014 .], the energy management is mainly composed of a rectifier circuit and a DC boost circuit, and a...
