What does a battery protection circuit do?
The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.
Why do you need a battery protection IC?
That is why we design our battery protection ICs to detect a variety of fault conditions including overvoltage, undervoltage, discharge overcurrent and short circuit in single-cell and multi-cell batteries, so you can enhance the safety of your battery pack.
What is a battery protection circuit / IC?
Battery protection circuits / IC solutions and reference designs that allow easy design-in and ensure safe charging and discharging - prevent damage and failures.
What is the flow of discharging current from a battery?
the flow of discharging current (i.e. current from the battery) into the load. Shown are examples. Irrespective to the protection implementation on high or low side, either source-to-source or drain-to-drain configurations are possible. Inrush currents arise during the turn on, mainly when the battery is first connected to the load.
What happens if a battery is discharged?
In a discharged condition, current to the protection circuitry continuously discharges the battery. If the battery is discharged below the recommended end-of-discharge voltage, overall battery performance degrades, the cycle life is shortened and the battery may die prematurely.
What is a protection circuit module for lithium batteries?
A typical Protection Circuit Module for lithium batteries includes integrated circuits (ICs) that manage voltage and current, temperature sensors such as PTC and NTC thermistors, and various electronic components that facilitate real-time monitoring and protection functions.
