Product Introduction

Overview

The MC34164D-5R2, produced by onsemi, is a micropower undervoltage sensing circuit designed for use as a reset controller in portable microprocessor-based systems. This device is particularly suited for applications where extended battery life is crucial. It offers an economical solution for low voltage detection using a single external resistor. The MC34164 series features a bandgap reference, a comparator with precise thresholds and built-in hysteresis, and an open collector reset output capable of sinking in excess of 6.0 mA. It guarantees operation down to 1.0 V input with extremely low standby current, making it ideal for power-sensitive applications.
