Protect your battery
Reliable battery protection with advanced precision and integration
We understand that performance and safety are major care-abouts for battery packs with lithium-based (Li-ion & Li-polymer) chemistries. That’s why we design our battery protection ICs to detect a variety of fault conditions such as overvoltage, undervoltage, discharge overcurrent and short circuit in single-cell and multi-cell batteries. So you can enhance the safety of your battery pack.
