The AD8280 is a hardware-only safety monitor for lithium ion battery stacks. The device has inputs to monitor six battery cells and two temperature sensors (either NTC or PTC thermistors). The device is designed to be daisy-chained with additional AD8280 devices to monitor a stack of significantly more than...
