Product Introduction

Overview

The MC33064P-005, produced by onsemi, is an undervoltage sensing circuit designed specifically for use as a reset controller in microprocessor-based systems. It provides an economical solution for low voltage detection with the use of a single external resistor. The device features a trimmed-in-package bandgap reference and a comparator with precise thresholds and built-in hysteresis to prevent erratic reset operations. It is capable of operating down to 1.0 V input with low standby current and has an open collector reset output that can sink in excess of 10 mA.
