Active-LOW system reset
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.
