Reliable battery protection with advanced precision and integration
We understand performance and safety are major care-abouts for battery packs with lithium-based (li-ion and li-polymer) chemistries. 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.
