Describes

This IC is used for secondary protection of lithium-ion rechargeable batteries and incorporates high-accuracy voltage detection circuits and delay circuits.

Short-circuiting between the VC1 and VC2 pins makes it possible to serially connect three cells.

Since this IC also comes with a constant voltage output circuit capable of outputting 1.5 V to 3.3 V, it can be used as a constant-voltage power supply for an external RTC (Real-Time clock IC). 

Application

‍

• Lithium-ion rechargeable battery packs (for secondary protection)
