Battery and Charge Protection ICs guard lithium-ion battery packs, which are used most often, against overcharge, overdischarge, overcurrent, and short-circuit conditions.
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.
The battery is safeguarded by the battery protection mode. Battery protection mode is enabled if the state of charge (SOC) of the battery drops below the thresholds.
The Global Charge Protection ICs 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.
A protection IC for lithium-ion and lithium-polymer rechargeable batteries, the S-82B1A Series from ABLIC has delay circuits and high-accuracy voltage detection circuits. It is ideal for guarding against overcharge, overdischarge, and overcurrent in 1-cell lithium-ion/lithium polymer rechargeable battery packs.
Charge-discharge control using an external signal is possible thanks to the input pin for charge-discharge control signal on the S-82B1A Series. A secondary-level voltage monitor and protection for Li-ion battery pack systems is part of the BQ2945xy product family made by Texas Instruments. An overvoltage condition is independently checked on each cell.
Depending on the design, if any of the two or three cells experience an overvoltage condition, an output is activated after a fixed delay. When the given delay timer is satisfied by an overvoltage condition, this output is triggered into a high state.
