It providescomplete battery monitoring and pack control. The ISL94202 provides automatic shutdown and recovery fromout-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 external microcontroller, whichcommunicates to the IC through an I2C interface.ISL94202主要特性:? Eight cell voltage monitors support Li-ion CoO2, Li-ion Mn2O4, and Li-ion FePO4 chemistries? Stand-alone pack control - no microcontroller needed? Multiple voltage protection options (each programmable to 4.8V; 12-bit digital value) and selectable overcurrentprotection levels? Programmable detection/recovery times for overvoltage, undervoltage, overcurrent, and short-circuit conditions? Configuration/calibration registers maintained in E/topic/tag_list.html?id=38181EPROM? Open battery connect 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 external microcontroller? Enters low power states after periods of inactivity? Charge or discharge current detection resumes normal?/topic/tag_list.html?id=43962scan ratesISL94202应用:? Power tools? Battery back-up systems? Light electric vehicles? Portable equipment?
