Product data
NE56632-XX
DESCRIPTION
The NE56632-XX is a family of Active-LOW, power-on reset that
offers precision threshold voltage detection within ±1.5% and super
low operating supply current of typically 3.0 µA. It includes a reset
delay that is user adjustable with an external capacitor.
Several detection threshold voltages are available at 1.9V , 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 NE56632-XX is well suited for various
battery powered applications such as reset circuits for logic and
microprocessors, voltage check, and level detecting. It is available in
the SOT23-5 package.
