Maxim Integrated MAX6343TUT Microprocessor Reset Circuit

The Maxim Integrated MAX6343TUT is a highly reliable, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant line of defense against system failures caused by fluctuations and failures in the power supply. This compact device is essential for maintaining system integrity and ensuring consistent operation of digital systems.

Key Features

• Precision Monitoring: The MAX6343TUT offers precision voltage monitoring, with factory-set reset thresholds suitable for a wide range of applications. This ensures that the µP resets reliably and operates correctly upon power-up, power-down, and brownout conditions.
• Low Power Consumption: Designed for power-sensitive applications, the device consumes minimal power, with a typical supply current of only 1µA. This feature helps prolong battery life in portable applications.
• Manual Reset Input: An additional manual reset input allows for a reset to be triggered with an external pushbutton or logic signal, providing an extra layer of system control.
• High Reset Output: The reset output is active-high, which is compatible with a variety of microprocessors and digital ICs that require a high signal to initiate a reset.
• Watchdog Timer: An on-board watchdog timer can be used to monitor software execution integrity by requiring periodic servicing from the µP. If the µP fails to service the watchdog, a reset signal is generated to restart the system.
• Compact Package: The MAX6343TUT comes in a small, 6-pin SOT23 package, making it suitable for space-constrained applications.
• Temperature Range: It operates over an extended temperature range, making it suitable for industrial applications subjected to harsh environments.

Applications

The MAX6343TUT is ideal for use in a variety of applications where reliable system operation is critical. These include:

• Portable/Battery-Powered Equipment
