Intersil公司的ISL94202是锂电池组监测集成电路,支持三到八个电池组,支持锂离子 CoO2, 锂离子Mn2O4和锂离子FePO4化学电池,提供完整的电池监测和电池组控制,具有自动关断和恢复以及自动控制电池组的平衡,不需要微控制器.主要用在电动工具,电池备份系统,小型电动车,手持设备,能量存储系统,太阳能农场,医疗设备,监视设备和通风设备.本文介绍了ISL94202主要特性,功能框图和应用框图,以及评估板ISL94202EVKIT1Z主要特性和测试框图,电路图,材料清单和PCB设计图.
The ISL94202 is a Li-ion battery monitor IC that supports from three to eight series connected cells. 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..
