BATTERY PROTECTION IC FOR 3-SERIAL OR 4-SERIAL CELL PACK WITH CONSTANT VOLTAGE OUTPUT PIN FOR REAL-TIME CLOCK
(SECONDARY PROTECTION)
Rev.1.3_00
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, it can be used as a constant-voltage power supply for an external RTC (Real-Time clock IC).
Features
• High-accuracy voltage detection circuit for each cell
Overcharge detection voltage n
3.600 V to 4.
