Multi-Cell Li-Ion Battery Manager
Jump to Page Section:
Overview
Description
The ISL78600 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 incorporated: Manual Balance mode, Timed Balance mode, and Auto Balance mode. The Auto Balance mode terminates balancing functions when a charge transfer value specified by the host microcontroller has been met. The ISL78600 communicates to a host microcontroller through an SPI interface and to other ISL78600 devices using a robust, proprietary, two-wire daisy chain system. The ISL78600 is offered in a 64 Ld TQFP package and is specified for operation at a temperature range of -40°C to +105°C.
