Overview
The MC33064D-5R2G, produced by onsemi, is an undervoltage sensing circuit designed specifically for use as a reset controller in microprocessor-based systems. This component offers an economical solution for low voltage detection with the use of a single external resistor. It features a trimmed-in-package bandgap reference and a comparator with precise thresholds and built-in hysteresis to prevent erratic reset operations. The device is capable of operating down to 1.0 V input with low standby current and is packaged in an 8-pin SOIC-8 surface mount package, which is Pb-free and RoHS compliant.
