The ISO26262 (ASIL) compliant automotive grade ISL78600 multi-cell system is specifically designed to prevent battery pack failures and to meet the safety, reliability and performance requirements of the hybrid, plug-in hybrid (PHEV) and EV markets.

Each ISL78600 device utilizes a 14-bit temperature compensated data converter that scans 12 channels in less than 250 microseconds to provide the accuracy needed for precise state-of-charge measurements to extend vehicle driving range and the life of Li-Ion batteries.

The ISL78600 facilitates intra-system communication through a transient tolerant communication scheme that allows the use of low cost twisted pair wiring to stack multiple battery packs together while protecting against hot plugging and high voltage transients.

The battery management system connects to microcontrollers via either a 2.5MHz SPI or 400KHz I2C interface and is specified for -40 degree centigrade to 105 degree centigrade operation.

The device features Intersil’s ISL78601 multi-cell battery monitor that provides for independent redundant fault monitoring, including built-in fault detection for all its major internal functions and external faults such as open wire, over and under voltage and temperature and cell balancing faults.

The ISL78600 is available now in a 10mm x 10mm 64-lead TQFP package at $6.50 each in 10,000-piece quantities.
