When the battery voltage falls below the lockout threshold, the circuit checks the voltage of a Li-Ion battery and disconnects the load to prevent deep discharge. A battery that runs on batteries runs the danger of being entirely discharged if it is stored in a discharged state.
Lithium batteries should only be charged to 4.1 V or 4.2 V/cell in a secure environment. Overcharging compromises the battery’s performance and poses a safety risk, including a risk of fire. To avoid this, a battery protection circuit should be employed.
The Global 2-cell Li-ion Battery Protection IC market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
This integrated circuit (IC) is a protective IC for lithium-ion and lithium-polymer rechargeable batteries. It features delay circuits and high-accuracy voltage detection circuits.
It is ideal for guarding against overcharge, overdischarge, and overcurrent in 2-serial-cell lithium-ion/lithium polymer rechargeable battery packs.
This IC can provide high-accuracy overcurrent protection with decreased sensitivity to temperature fluctuations thanks to the use of an external overcurrent detecting resistor.
The charge-discharge control signal input pin (CTL pin) on the S-82B2A Series from Ablic enables charge-discharge control with an external signal. The S-82B2B Series contains a power-saving signal input pin (PS pin), which enables a reduction in current usage by starting the power-saving function with an external signal.
