Product Introduction

Overview

The NCP3231MNTXG is part of the NCP300 and NCP301 series of ultra-low current voltage detectors produced by onsemi. These devices are specifically designed for use as reset controllers in portable microprocessor-based systems where extended battery life is crucial. The NCP3231MNTXG features a highly accurate undervoltage detector with hysteresis to prevent erratic system reset operations.
