A new type of miner's power management circuit is designed by a high-level integration chip. Lithium battery is charged by adopting constant current-constant voltage mode of TP4056 chip,and the main-to-auxiliary in-tegrated LED is driven through the miner's special chip SN3135. The working status of the main light source and auxiliary light source can be adjusted by manual and automatic mode. The circuit has protection function of over-charge,over discharge,temperature detection and charge status indication. The experimental results show that the miner's power management circuit can satisfy the underground use requirement,which has such characteristics as simplicity,stability and economy.
