Lithium-ion battery protection circuit composed of DS2760

Relevant key device information applied in this article: DS2760 DS2760 has an internal 25mΩ detection resistor, which can detect bidirectional (charging and discharging) current (but its own resistance is extremely small and the loss is extremely small); the current resolution is 0.625mA, and the dynamic range is 1.8A, and has current accumulation calculation; the voltage measurement resolution is 48mV; the temperature measurement resolution can reach 0.125℃; the digital quantity converted by the A/D converter is stored in the corresponding memory and communicates with the main system through a single-wire interface Connection can manage and control the power supply composed of lithium-ion batteries, that is, read/write access and control to the internal memory. The device has low power consumption, with a maximum current of 80μA in the working state and less than 2μA in the energy-saving state (sleep mode). The protection circuit composed of it is shown in the figure below
