ADM6305/ADM6306
SPECIFICATIONS
VCC = 2.5 V to 5 V for the ADM6305, VCC = (VTH + 2.5%) to 5.5 V for the ADM6306. TA = −40°C to +125°C, unless otherwise noted.
Typical values are at TA = 25°C.

1 The ADM6305 switches from undervoltage reset to normal operation when 1.5 V > VCC < 2.5 V.
2 The AMD6306 monitors VCC 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.
3 Guaranteed by design.
