ADM811TARTZ is perfect as Logic Low RESET for ADAU1701 and I use it in different hardware.
I have to modify a hardware with on board ADAU1701 and I need an IC identical to ADM811TARTZ but with integrated also the function POWER FAIL INPUT, to check the level of battery charge.
I do not need to constantly know the charge, but only a level and exactly when the battery reaches the minimum level allowed.
In an old circuit I used the POWER FAIL INPUT of an ADM706 connected as shown in the drawing and it works perfectly.

Some advice, thank you
