The ISL94202 is a battery pack monitor IC that supports from three to eight series connected cells. It provides complete battery monitoring and pack control. The ISL94202 provides automatic shutdown and recovery from out-of-bounds conditions and automatically controls pack cell balancing. The ISL94202 is highly configurable as a stand-alone unit, but can be used with an optional external Microcontroller (MCU), which communicates to the ISL94202 through an I2C interface. The ISL94202 supersedes the ISL94203 for all future designs, as the ISL94202 operates in both parallel and series power FET configurations.


  • Eight cell voltage monitors support Li-ion CoO2, Li-ion Mn2O4, Li-ion FePO4, and other chemistries
  • Stand-alone pack control - no MCU needed
  • Multiple voltage protection options (each programmable to 4.8V; 12-bit digital value) and selectable overcurrent protection levels
  • Programmable detection/recovery times for overvoltage, undervoltage, overcurrent, and short-circuit conditions
  • Configuration/calibration registers maintained in EEPROM
  • Open Wire battery connection detection
  • Integrated charge/discharge FET drive circuitry with built-in charge pump supports high-side N-channel FETs
  • Cell balancing uses external FETs with internal state machine or an optional external MCU
  • Enters low power states after periods of inactivity
    • Charge or discharge current detection resumes normal scan rates
