ABLIC S-82D1A Battery Protection ICs
ABLIC S-82D1A Battery Protection ICs are for lithium-ion / lithium polymer rechargeable batteries with temperature protection circuits, high-accuracy voltage detection circuits, and delay circuits. The temperature protection is possible by connecting an NTC thermistor to the dedicated connection pin. These ICs feature a charge-discharge control function, discharge overcurrent control function, and power-down function. The S-82D1A battery protection ICs include high-withstand voltage, low current consumption, and 0V battery charge. These battery protection ICs operate at -40°C to 85°C temperature range. Typical applications include the lithium-ion rechargeable battery pack and lithium polymer rechargeable battery pack.
