ISL78600集成電路（IC）的電池管理規(guī)格書PDF中文資料

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 via 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.
