1
The ADM6305 switches from undervoltage reset to normal operation when 1.5 V > V
CC
< 2.5 V.
2
The AMD6306 monitors V
CC
through an internal factory trimmed voltage divider, which programs the nominal reset threshold. Factory-trimmed reset thresholds are
available in approximately 100 mV increments from 2.5 V to 5 V.

Guaranteed by design.
