ISL78610
Multi-Cell Li-Ion Battery Manager
The ISL78610 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 ISL78610 communicates to a host microcontroller through an SPI interface and to other ISL78610 devices using a robust, proprietary, 2-wire daisy chain system.
The ISL78610 is offered in a 64 Ld TQFP package and is specified for operation at a temperature range of -40°C to +105°C.
