Description
The ISL94212A Li-ion battery manager IC supervises up to 12 series-connected cells. The part provides accurate monitoring, cell balancing, and extensive system diagnostics functions. Three cell balancing modes are provided: manual balancing mode, timed balancing mode, and auto balance mode. The auto balance mode terminates balancing functions when a charge transfer value has been met. The ISL94212A communicates with a host microcontroller via a serial peripheral interface (SPI) and with other ISL94212A devices using a robust, proprietary two-wire Daisy Chain system. The ISL94212A is offered in a 64 Ld TQFP package and is specified for an operational temperature range of -40°C to +85°C.
