Product Description

The AD8280WASTZ is a hardware-only Safety Monitor for Li-ion battery stacks. The part has inputs to monitor six battery cells and two temperature sensors (either NTC or PTC thermistors). The part is designed to be daisy-chained with other AD8280 devices to monitor a stack of significantly more than six cells without the need for numerous isolators. Its output can be configured for an independent or shared alarm state. The AD8280 functions independently from a primary monitor and contains its own reference and LDO, both of which are powered completely from the battery cell stack. The reference, in conjunction with external resistor dividers, is used to establish trip points for the over voltages and under voltages. Each cell channel contains programmable deglitching circuitry to prevent alarms from transient input levels.
