Maxim Integrated MAX6334UR16D2+T Microprocessor Reset Circuit

The MAX6334UR16D2+T is a high-quality, precision microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides a significant level of system reliability and accuracy required in critical applications, ensuring that the µP and its peripherals are reset properly during power-up, power-down, and brown-out conditions.

This device is particularly well-suited for portable and battery-powered equipment due to its low power consumption and small footprint. The MAX6334UR16D2+T is available in a tiny SOT23-3 package, making it an ideal choice for space-constrained applications where board real estate is at a premium.

Key features of the MAX6334UR16D2+T include:

• Factory-trimmed reset threshold voltage of 1.6V, providing high accuracy for monitoring 1.8V-powered circuits.
• Low supply current of 5µA (typical), which helps to extend battery life in portable devices.
• Guaranteed reset valid to VCC = 1V, ensuring reliable operation during low voltage conditions.
• Immune to short VCC transients, the device does not generate false resets, maintaining system stability.
• Integrated watchdog timer, which can be disabled if not required, providing additional flexibility for system design.
• Active-low RESET output, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, providing ample time for the system to stabilize.

The operating temperature range of the MAX6334UR16D2+T spans from -40°C to +85°C, allowing the device to perform reliably in a wide range of environmental conditions. This makes it a versatile component for various applications, including computers, controllers, intelligent instruments, and critical microcontroller-based systems.

With its precision voltage monitoring and low power consumption, the MAX6334UR16D2+T from Maxim Integrated is an excellent choice for designers looking to enhance the reliability and performance of their digital systems. Its ease of integration and robust feature set make it a valuable component for maintaining system integrity across multiple applications.
