Maxim Integrated MAX6822ZUK+ Microprocessor Reset Circuit

The Maxim Integrated MAX6822ZUK+ is a precision microprocessor (μP) reset circuit device designed to monitor power supplies in digital systems. It provides a high degree of accuracy and reliability, ensuring that your microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. This compact and efficient component is an essential part of maintaining system stability and is ideal for use in a wide range of applications, including computers, controllers, and intelligent instruments.

Encased in a small SOT-23 package, the MAX6822ZUK+ offers a manual reset input feature, which allows the flexibility of triggering a system reset from an external source. This manual reset function is an invaluable tool for system maintenance and debugging processes. Additionally, the device boasts a low supply current, making it an energy-efficient choice for portable and power-sensitive applications.

Key features of the MAX6822ZUK+ include:

• Factory-trimmed reset threshold voltages suitable for a variety of applications, ensuring reliable operation under specified conditions.
• An active-low reset output, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, providing ample time for the system to stabilize.
• An Immune to short VCC transients feature, which prevents false resets from occurring, thus enhancing the stability of the system during erratic power supply conditions.
• Low supply current of 6μA (typical), which is highly advantageous for battery-operated devices where power conservation is critical.

With its built-in features, the MAX6822ZUK+ offers a robust solution for system management and protection. Its precise voltage monitoring and reset capabilities safeguard the system processor by ensuring that it operates within safe parameters. Whether you're designing consumer electronics, industrial equipment, or automotive systems, the MAX6822ZUK+ from Maxim Integrated provides the reliability and performance required for today's sophisticated digital systems.
