Maxim Integrated's MAX6342MUT-T Microprocessor Reset Circuit

The MAX6342MUT-T is a high-quality microprocessor (µP) supervisory circuit designed by Maxim Integrated 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 precision voltage monitoring.

This compact device is housed in a space-saving SOT23-6 package, making it an ideal choice for portable and space-constrained applications. The MAX6342MUT-T offers a variety of features that ensure system stability and functionality, even during power-up, power-down, or brown-out conditions.

Key features of the MAX6342MUT-T include:

• Factory-Trimmed Reset Threshold: The device comes with a preset reset threshold voltage, which is factory-trimmed for accuracy. This ensures reliable operation without the need for external adjustments.
• Low Power Consumption: Designed for power-sensitive applications, it consumes minimal power, which helps in extending the battery life of portable devices.
• Manual Reset Input: The inclusion of a manual reset input allows for a system reset to be triggered with an external pushbutton or logic signal, providing additional system control.
• Reset Timeout: After a reset is initiated, the MAX6342MUT-T maintains the reset condition for a minimum timeout period to ensure the system has adequate time to stabilize.
• Immune to Short Vcc Transients: The device is designed to ignore short transients on the Vcc line, which helps prevent false resets and ensures stable operation.

The MAX6342MUT-T operates over a wide temperature range, making it suitable for a variety of environments and applications, including computers, controllers, intelligent instruments, portable/battery-powered equipment, and other critical µP systems where precise monitoring is essential.

With its precision voltage monitoring and robust feature set, the MAX6342MUT-T from Maxim Integrated is an excellent choice for designers looking to enhance the reliability and performance of their systems.
