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.

FEATURES

•High precision threshold detection voltage: VS ±3%

•Super low operating supply current: ICCH=1.5 μA typ.; ICCL=1.0 μA typ.

•Hysteresis voltage: 50 mV typ.

•Internal Power-On-Reset Delay time: 20 μs typ.
