NE56631-XX

GENERAL DESCRIPTION

The NE56631-XX is a family of Active-LOW, power-on resets that

offers precision threshold voltage detection within ±3% and super

low operating supply current of typically 1.5 µA.

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.
