Battery-monitoring IC suits hybrid vehicles

Maxim Integrated Products introduces the MAX11068, a high voltage, 12 cell, battery-monitoring IC for hybrid vehicles, electric vehicles, and any system that stacks long series strings of batteries. This highly integrated solution employs a proprietary SMBus-laddered communication bus that allows multiple MAX11068s to be daisy-chained together without expensive isolators. This approach reduces battery-management system (BMS) cost by up to 80%, while simplifying battery pack design and precisely balancing cells for maximum energy delivery.

The MAX11068 solves the problems associated with safely monitoring large battery stacks and accurately balancing cells. It is well suited for a wide spectrum of battery applications including automotive, industrial, power line, and battery backup.

The MAX11068 is packaged in a 38-pin TSSOP and is fully specified for operation over the -40° to 105° C AEC-Q100 Type 2 temperature range.
