MAX6432ORUS

Overview

The MAX6432ORUS is a single-supply, low-power voltage supervisor manufactured by Analog Devices Inc. (Maxim Integrated). It operates within an input voltage range of 1.0 V to 5.5 V and features a selectable reset output threshold. The device provides precise monitoring with a typical accuracy of 1% for the reset threshold voltage. It incorporates a manual reset input for system control and includes a built-in delay timer to prevent false triggering during power-up or brown-out conditions. The component is housed in an 8-pin SOIC-Narrow package.
