Product data
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.
