ISL94202 Description
Datasheet ISL94202 Standalone 3 to 8 Cell Li-Ion Battery Pack Monitor The ISL94202 is a battery pack monitor IC that supports from three to eight series connected cells. It provides plete battery monitoring and pack control. The ISL94202 provides automatic shutdown and recovery from out-of-bounds conditions and automatically controls pack cell balancing.
ISL94202 Key Features
- 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 protect
- 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
