Maxim Integrated MAX6355SUVT Overview

The MAX6355SUVT is a precision, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring.

Key Features

• Voltage Monitoring: This device keeps a close watch on the system voltage, ensuring that it remains within operational limits, thus safeguarding the system from undervoltage conditions.
• Reset Output: The MAX6355SUVT provides a reset output which remains asserted for a minimum of 140ms after Vcc has risen above the reset threshold. This ensures the µP starts up cleanly in the event of power restoration.
• Low Power Consumption: Designed for power-sensitive applications, this supervisory circuit draws minimal current, typically just 1.1µA at +3.3V, making it suitable for battery-operated devices.
• High Accuracy: The reset threshold is factory-set with high precision, ensuring reliable monitoring without the need for external adjustments.
• Manual Reset Input: It includes a manual reset feature that allows for a system reset to be initiated with an external input, providing additional system control flexibility.
• Compact Package: The device comes in a small, surface-mount SOT23 package, which saves space on the PCB and is ideal for use in space-constrained applications.

Applications

The MAX6355SUVT is well-suited for a variety of applications that require reliable voltage supervision. These include:

• Portable/Battery-Powered Equipment
• Embedded Systems
• Computers and Controllers
• Data Storage Systems
• Medical and Safety Equipment

With its combination of features, the MAX6355SUVT from Maxim Integrated is an excellent choice for designers looking to enhance system reliability and performance through effective power monitoring. Its ease of integration, low power consumption, and precision make it a versatile component for a wide range of electronic systems.
