Maxim Integrated's MAX6323EUT31-T Microprocessor Reset Circuit

The MAX6323EUT31-T is a highly reliable and precise microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring.

This device is particularly well-suited for portable, battery-powered applications due to its low power consumption and small footprint. The MAX6323EUT31-T helps to ensure that the µP and its peripherals are reset properly during power-up, power-down, or brown-out conditions.

Key Features:

• Precision Monitoring: The device offers a factory-trimmed reset threshold voltage of 3.1V, ensuring accurate monitoring of the power supply voltage.
• Low Power Consumption: With its low supply current of only 1µA (typical), it is an excellent choice for battery-operated equipment.
• Manual Reset Input: A manual reset input allows the user to trigger a reset manually, providing additional system control.
• Reset Output: The reset output is available in both push-pull and open-drain configurations, making it versatile for interfacing with different types of microprocessors.
• Power Supply Transient Immunity: No external components are required for power supply transient immunity, simplifying the design and reducing the bill of materials.
• Compact Package: The SOT23 packaging makes the MAX6323EUT31-T an ideal solution for space-constrained applications.
