The Renesas ISL942x family of Li-ion battery monitor ICs support anywhere from 3 to 12 series of connected battery cells. It provides full battery monitoring and pack control. The ISL94203 provides automatic shutdown and recovery from out of bounds conditions and automatically controls pack cell balancing. The ISL942x battery monitors support Li-ion CoO2, Li-ion, Mn2O4, and Li-ion FePO4 chemistries.
These battery monitors are highly configurable as stand-alone units but can be used with an external microcontroller, which communicates to the IC through an I2C interface. ISL942x devices also offer programmable detection/recovery times for overvoltage, undervoltage, overcurrent, and short-circuit conditions as well as open battery detection. The rich feature set of the ISL92x family of battery monitor ICs makes them suitable for wearables, power tools, battery backup systems, and IoT applications.
