topGeneral description
The NE56631-XX is a family of Active-LOW, power-on resets that offers precision threshold voltage detection within +-3pct and super low operating supply
current of typically 1.5 uA.
Several detection threshold voltages are available at 1.9 V, 2.0 V, 2.7 V, 2.8 V, 2.9 V, 3.0 V, 3.1 V, 4.2 V, 4.3 V, 4.4 V, 4.5 V, and 4.6 V. Other thresholds
are offered upon request at 100 mV steps from 1.9 V to 4.6 V.
With its ultra low supply current and high precision voltage threshold detection capability, the NE56631-XX is well suited for various battery powered
applications such as reset circuits for logic and microprocessors, voltage check, and level detecting.
