Data Sheet
ADM6305/ADM6306
SPECIFICATIONS
V CC = 2.5 V to 5 V for the ADM6305, V CC = (V TH + 2.5%) to 5.5 V for the ADM6306. T A = ?40°C to +125°C, unless otherwise noted.
Typical values are at T A = 25°C.

The ADM6305 switches from undervoltage reset to normal operation when 1.5 V > V CC < 2.5 V.
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.
