Rev.9.00
May 23, 2017 Multi-Cell Li-Ion Battery Manager
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. Features Up to 12-cell voltage monitors, support Li-ion CoO2,
Li-ion Mn2O4, and Li-ion FePO4 chemistries Board level cell voltage measurement accuracy В±1.5mV 13-bit cell voltage measurement Pack voltage measurement accuracy В±100mV 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. 14-bit pack voltage and temperature measurements The ISL78600 is offered in a 64 Ld TQFP package and is
specified for operation at a temperature range of -40В°C to
+105В°C. Internal and external temperature monitoring Cell voltage scan rate of 19.5Вµs per cell (234Вµs to scan
12 cells) Up to four external temperature inputs Robust daisy chain communications system Applications Integrated system diagnostics for all key internal functions Hybrid Electric Vehicle (HEV), Plug-in Hybrid Electric Vehicle
(PHEV), and Electric Vehicle (EV) battery packs Electric motorcycle battery packs Hardwired and communications based fault notification Integrated watchdog shuts down device if communication is
lost Backup battery and energy storage systems requiring high
accuracy management and monitoring 2Mbps SPI Portable and semiportable equipment Related Literature AEC-Q100 qualified For a full list of related documents, visit our website
