MAX6342SUT+T

Overview

The MAX6342SUT+T is a supervisory circuit featuring a power-fail comparator and reset generator in a 6-pin SOT-23 package. It monitors a single input with a threshold voltage of 2.97 V and an overvoltage threshold of 2.97 V. The device operates from a maximum supply voltage of 5.5 V with a quiescent current of 2.5 uA. It provides an active low, open-drain output and includes a reset delay time of 4.375 ms. The component functions within a temperature range of -40 C to +125 C.

Feature Summary

• Integrates a power-fail comparator for real-time voltage monitoring
• Provides active low open-drain reset signal generation
• Operates with ultra-low quiescent current consumption
• Includes built-in reset delay timer for stable initialization

Applications

• Microprocessor system power supervision
