IC offers Li-ion battery protection, safety monitor

The AD8280 is an integrated solution that monitors six cell voltages and two temperature inputs. It is powered from the battery stack providing either a shared or a separate alarm for any of three conditions — overvoltage, overtemperature, or undervoltage. It also includes self-test enhancing the ability to meet functional safety requirements such as ISO26262 and IEC61508.

The Li-ion battery monitoring device features a continuous range-of-trip point settings to provide the flexibility to work with any Li-ion battery chemistry. It offers flexible safety monitoring configurations, a daisy-chain option to minimize the need for isolators in a high-voltage cell stack, and a low-power mode to minimize battery drain when the battery is not in use. The device is compliant with AEC-Q100 and EMI standards, making the part suitable for automotive applications. ($3.49 ea/1,000 — available April.)
