crucial when using lithium-ion batteries because if the battery is discharged below its rated value, the battery will become damaged and potentially pose a safety hazard. In addition to undervoltage protection, it is important to ensure that the battery is discharging a safe current value. Combining undervoltage protection and overcurrent
Lithium batteries have the advantage of high energy density. However, they require careful handling. This article discusses important safety and protection considerations when using a lithium battery, introduces some common battery protection ICs, and briefly outlines selection of important components in battery protection circuits. Overcharge
A battery protection circuit will take the battery out of the circuit if the load current is too high. How battery protection circuits work Battery protection ICs typically use MOSFETs to switch lithium cells in and out of circuit. Lithium cells of the same age and part number can be paralleled and share one protection circuit.
Considerations in choosing battery protection ICs Two important parameters in battery ICs are overvoltage threshold and undervoltage threshold. These numbers are the voltage levels at their limit; the IC will cut the cell out of circuit if the cell is being overcharged or over-discharged.
MOSFET selection A key element of a battery protection circuit are the MOSFETs used to switch the cell in and out of the circuit. MOSFETs with low RDS (ON) should be used to achieve high efficiency. Use MOSFETs with low Vt because the battery protection IC may only have 2–3 V to drive the gate.
