Maxim Integrated MAX6705ASKA+T Microprocessor Supervisory Circuit

The MAX6705ASKA+T from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant layer of protection by ensuring that the system's voltage levels remain within operational thresholds, thereby enhancing system stability and safety.

This supervisory circuit is particularly well-suited for portable and battery-powered equipment due to its low power consumption and small size. The MAX6705ASKA+T comes in a compact 8-pin SOT-23 package, making it an ideal choice for space-constrained applications.

Key Features

• Power-Supply Monitoring: This device keeps a vigilant eye on the system power supply, offering an active-low reset output. This feature ensures that the µP resets cleanly during power-up, power-down, or brown-out conditions.
• Low Quiescent Current: With a quiescent current of only 17µA, the MAX6705ASKA+T is optimized for power-sensitive applications, contributing to extended battery life and reduced power consumption.
• Factory-Set Reset Thresholds: The reset thresholds are preset at the factory, simplifying the design process as no external adjustments are necessary. This ensures reliable operation without the need for additional components or fine-tuning.
• Manual Reset Input: An additional feature includes a manual reset input that allows for a system reset via an external pushbutton or logic signal, offering flexibility in system design and user control.
• Reset Timeout: The device boasts a 140ms minimum power-on reset timeout period, which guarantees that the system has sufficient time to stabilize before the µP begins operation.

Applications

The MAX6705ASKA+T is versatile and can be employed in a variety of applications, including:

• Portable/Battery-Powered Devices
• Embedded Systems
• Computers and Servers
• Data Storage
• Medical Devices
• Industrial Controllers

Maxim Integrated's commitment to quality and reliability is evident in the MAX6705ASKA+T supervisory circuit, making it a trusted component for safeguarding system integrity across a wide range of electronic applications.
