S-82H4 Datasheet Battery Protection

Manufacturer: ABLIC

Overview: S-82H4 Series www.ablic.com © ABLIC Inc., 2022-2023 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).
