Protect your battery
Reliable battery protection with advanced precision and integration
Battery protection IC detects a variety of fault conditions such as overvoltage, under-voltage, discharge overcurrent, and short circuit, and range from simple (OV only) to advanced (more faults detected). Battery protection is a requirement for any lithium based chemistries; our battery protection portfolio can help you get started.
Battery protectors for single cell battery packs such as smartphones and wearables capable of protecting against voltage, current, and temperature faults and auto-recovering by opening & closing FETs.
Battery protectors for multi cell battery packs such as power tools and vacuum cleaners capable of protecting against voltage, current, and temperature faults and auto-recovering by opening & closing FETs with stacking and cell balancing built in.
Battery protectors for single up to multiple cells stacked meant to drive a fuse for permanent failure or redundant protection.
