Battery protection circuit and battery circuit

The embodiment of the invention provides a battery protection circuit and a battery circuit, and the circuit comprises an adjustment module, a polling signal generation module, a re-decoding module, a sampling reference voltage generation module, a digital-to-analog conversion module, a selection module, and a comparison module. Different detection protection and threshold gears can share the same sampling reference voltage generation module, the selection module and the comparison module, the waste of the chip area caused by the enlargement of the battery protection circuit can be effectively avoided, and meanwhile, the power consumption of the battery protection circuit can be reduced. 本公开实施例提供一种电池保护电路和电池电路，包括调修模块、轮询信号产生模块、重新译码模块、采样参考电压产生模块、数模转换模块、选择模块和比较模块，实现使不同的检测保护保护和阈值档位可共用同一采样参考电压产生模块、选择模块和比较模块，可有效避免电池保护电路变大带来的芯片面积的浪费，同时也可降低电池保护电路的功耗。
