NE56632-XX Active-LOW system reset with adjustable delay time
Active-LOW system reset with adjustable delay time

The 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 A. It includes a reset delay that is user adjustable with an external capacitor. Several detection threshold voltages are available 4.5 V, and 4.6 V. Other thresholds are offered upon request 100 mV steps from 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.
