December 21, 2016 Multi-Cell Li-Ion Battery Manager
The automotive grade ISL78610 12-cell battery pack monitor
can be used as a stand-alone battery monitor or as a
redundant back-up device in an ASIL compliant system. It
supervises up to 12 series connected cells and features cell
voltage and temperature monitoring along with system
diagnostics.
The ISL78610 communicates to a host microcontroller via an
SPI interface and to other ISL78610 devices using a robust,
proprietary, two-wire daisy chain system.
The ISL78610 is offered in a 64 Ld TQFP package and is
specified for operation at a temperature range of -40В°C to
+105В°C. Features Up to 12-cell voltage monitors, support Li-ion CoO2, Li-ion
Mn2O4, and Li-ion FePO4 chemistries Cell voltage measurement accuracy В±10mV 13-bit cell voltage measurement 14-bit pack voltage and temperature measurements Cell voltage scan rate of 19.5Вµs per cell (234Вµs to scan
12 cells) Internal and external temperature monitoring Up to four external temperature inputs Robust daisy chain communications system Applications Hybrid Electric Vehicle (HEV), Plug-in Hybrid Electric Vehicle
(PHEV) and Electric Vehicle (EV) battery packs Electric motorcycle battery packs Backup battery and energy storage systems requiring high
accuracy management and monitoring Integrated system diagnostics for all key internal functions Integrated watchdog shuts down device if communication is
lost 2Mbps SPI AEC-Q100 qualified Related Literature Portable and semiportable equipment For a full list of related documents, visit our website ISL78610 product page TO OTHER DEVICES (OPTIONAL) ISL78610 ISL78610 VG2 VG2 VG1 VG1
