S-82K4 Datasheet BATTERY PROTECTION

Manufacturer: ABLIC

Overview: S-82K3/K4 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 ENABLING ANY ORDER OF BATTERY CONNECTION (SECONDARY PROTECTION) Rev.1.2_00 This IC is used for secondary protection of lithium-ion rechargeable batteries, and incorporates high-accuracy voltage detection circuits and delay circuits. The S-82K3 Series enable connection of 3-serial cell, and the S-82K4 Series enable connection of 4-serial cell. This IC provides a wake-up function to prevent the fuse from blowing during battery connection, and allows the lithium battery to be connected in any order. 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).
