Maxim Integrated MAX6314US30D1+T Microprocessor Reset Circuits

The MAX6314US30D1+T is a high-quality microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability and accuracy required in critical electronic applications.

This compact device is tailored to maintain system integrity by monitoring the power supply voltage. It generates a reset signal whenever the VCC supply voltage drops below the factory-set reset threshold level. The reset signal remains active for a minimum reset timeout period after VCC has risen above the reset threshold, ensuring the system has adequate time to stabilize.

The MAX6314US30D1+T operates with a nominal reset threshold voltage of 3.0V, which is ideal for 3.3V-powered circuits. It features an active-low, push-pull reset output. The push-pull configuration eliminates the need for an external pull-up resistor and allows for a direct connection to the reset pin of the microprocessor, simplifying circuit design and saving board space.

Key features of the MAX6314US30D1+T include:

• Immunity to short VCC transients
• Low supply current of 1.5µA (typical), which is ideal for battery-operated equipment
• Guaranteed reset valid to VCC = 1V, ensuring reliable system reset for low voltage conditions
• Wide operating temperature range from -40°C to +85°C, suitable for industrial applications

The device is available in a small, 4-pin SOT-143 package, which is highly beneficial for space-constrained applications. The MAX6314US30D1+T is also provided in tape and reel form, denoted by the '+T' suffix, facilitating easy integration into automated manufacturing processes.

Overall, the MAX6314US30D1+T from Maxim Integrated is a robust and reliable solution for system monitoring, offering a simple yet effective way to enhance the operational stability of µP systems. Its low power consumption, compact form factor, and ease of integration make it an excellent choice for a wide range of applications, from portable devices to complex digital systems.
