(AD8280)To use at 12V Li.-ion .

Hi !

Our customer is looking for hardware-only safety monitor.

They are going to use 12V lithium ion battery stacks.

The system is going to use 4 cells.

The power will drop to 6[V].

They are going to use cell balance IC (not ADI) but they want to secure redundancy.

So I think AD8280 will be good solution for them.

They want to detect over/under voltage each battery cells and when they detect it , they want to shut-down the system.

Q1)

Would AD8280 work for it?

Q2)

Is it possible to guarantee -40°C < TA < +125°C ?

Best regards.

  • Hi Kawa-san,

    Unfortunately, the AD8280 temperature range can not be extended to 125C without a significant amount of re-qualification. The AD8280 is a good candidate for applications requiring a hardware monitor to check 4 x 3V cells for over an under or over voltage conditions otherwise.
