Battery Management Systems and Power Distribution Units

Today’s battery management systems (BMS) need reliable, fast monitoring of the battery current – and functional safety requirements encourage heterogeneous redundancy. Our current sensor IC’s help you achieve ASIL ratings with highly accurate measurement of the battery current.

Designed with safety in mind, our market-leading current sensors offer 240kHz bandwidth and fast response time to give you very quick overcurrent detection to disconnect the battery contactors and short circuit detection to engage the pyro fuse.
