Description
The ISL78714 automotive-grade Li-ion battery manager IC supervises up to 14 series connected cells and is optimized to meet stringent automotive performance, reliability, and safety requirements. The device provides all the functions expected of such a critical component in a battery management system, such as accurate cell voltage and temperature monitoring, cell balancing, and extensive system diagnostics. In a typical configuration, a master ISL78714 communicates to a host microcontroller through an SPI port and up to 29 additional ISL78714 devices connected together by a robust, proprietary, two-wire daisy chain. This communication system is highly flexible and can be implemented with capacitor isolation, transformer isolation, or a combination of both. Three cell balancing modes are included: Manual Balance mode, Timed Balance mode, and Auto Balance mode. Auto Balance mode terminates balancing after a host-specified amount of charge has been removed from every cell. The ISL78714 is packaged in a 64-pin TQFP and is specified for operation from -40 °C to +105 °C.
