ADM6305/6 Dual input supervisor in a SOT
KEY BENEFITS






Monitors low voltage core and I/O supplies
High accuracy 0.4V(±1.5%) threshold enables
monitoring of core supplies <1.2V
Output valid to 0.9V ensures clean power down
Preset threshold in 100mV increments from 2.5-5.0V
Pin to pin to MAX6305/6 with higher spec.
5 Lead SOT23 package saves board space
