Abstract
Embodiments of this application relate to the field of circuit technologies. A wake-up circuit and a rechargeable device are disclosed. The wake-up circuit includes an input control module, a drive module, and an output control module. The input control module, the drive module, and the output control module each are connected to an auxiliary power supply. The input control module is configured to output a first level signal when an external voltage signal is received. The drive module is configured to, when the first level signal is received, output a second level signal that lasts for a first preset time. The output control module is configured to, when the second level signal is received, output a wake-up signal that lasts for the first preset time to a battery management system. According to this application, the wake-up circuit and the BMS consume less power of the auxiliary power supply.
