The MAX11068, a high-voltage 12-cell battery-monitoring IC suits hybrid vehicles, electric vehicles, and any system that stacks long series strings of batteries. The integrated solution employs a proprietary SMBus communication bus that allows multiple ICs to be daisy chained together without isolators. It is suited for battery applications including automotive, industrial, power line, and battery backup.
The battery-monitoring IC helps safely check large battery stacks and accurately balancing cells. It employs a capacitor-isolated SMBus-laddered communication bus to minimize component count. The product allows up to 31 devices to be connected in a series stack to monitor as many as 372 cells. It enables all cell-measurement samples of a 120-cell pack to be co-sited within 10 µs. (From $8.12/100 available now.)
