Technical Field
[0001] The utility model relates to the technical field of protection devices, in particular to a protection device for a mobile power supply mainboard. Background Art
[0002] A power bank motherboard protection device typically refers to a system or component designed to protect the power bank's internal circuitry from various potential hazards. The primary purpose of this protection device is to ensure the safe and stable operation of the power bank, preventing damage caused by overcharging, over-discharging, short circuits, overheating, and other conditions. This protection is typically implemented using a specialized protection chip (such as an MCU or dedicated power management IC) and a series of electronic components (such as MOSFETs, fuses, and thermistors). These components work together to monitor the power supply status in real time and take protective measures when necessary. The power bank motherboard protection device is a key component in ensuring the safe and reliable operation of the power bank, effectively extending battery life and ensuring user safety during use.
[0003] The prior art provides a mobile power supply motherboard protection device (Announcement No.: CN209982145U), which includes a power supply housing, a switch button provided on the upper surface of the power supply housing near one side, and a power indicator light provided on the upper surface of the power supply housing near the other side. An input interface is provided near the middle of one side of the outer surface of the power supply housing, and output interfaces are provided on both sides of the outer surface of the power supply housing near the input interface.
