The new MAX11080 from Maxim is a high-voltage, 12-channel battery protection IC for high-cell-count lithium-ion (Li+) battery stacks. It provides redundant cell monitoring to prevent Li+ batteries from exploding (thermal runaway), and up to 31 ICs can be daisy-chained together to monitor as many as 372 cells. This capability prevents cascading electrical failures and eliminates the expensive isolation components required by discrete solutions. In a typical hybrid vehicle, Maxim’s solution is said to reduce the cost of the battery management system (BMS) by up to 80%.
Offering high accuracy, low power consumption, built-in safety and self-diagnostic features, and extensive configurability, the MAX11080 is well suited for a spectrum of battery applications including automotive, industrial, power line and battery backup.
