Lithium Ion Battery Safety Monitor AD8280
FEATURES
Wide supply voltage range: 6.0 V to 30.0 V Multiple inputs can monitor 3 to 6 cell voltages and 2 temperatures Adjustable threshold levels: overvoltage, undervoltage, overtemperature Alarm options: separate or shared alarms Extended temperature range performance -40°C TA +105°C Can be daisy-chained Internal reference Powered from battery stack LDO available to power isolator Qualified for automotive applications Extensive self-test feature aids in meeting ASIL/SIL requirements
GENERAL DESCRIPTION
The AD8280 is a hardware-only safety monitor for lithium 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 i
