The MAX6328XR31-T is a compact, highly precise 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, or brown-out conditions.

Key Features

• Factory-Set Reset Thresholds: The device comes with a preset V_CC reset threshold voltage of 3.1V, tailored for specific system requirements.
• Low Power Consumption: With its low supply current of 1.2µA (typical), it is ideal for use in portable equipment where extending battery life is crucial.
• Compact SC70/SOT Package: The small 3-pin SC70 or SOT package makes it suitable for space-constrained applications.
• Manual Reset Input: This feature provides a manual reset capability, allowing for a system reset on demand.
• High Reset Active Timeout: The minimum power-on reset timeout period of 140ms ensures a reliable system reset.

Applications

The MAX6328XR31-T is versatile for a broad range of applications, including:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
• Intelligent Instruments
• Automotive Systems

Performance Benefits

With its precision monitoring of the power supply, the MAX6328XR31-T helps to prevent erroneous operation of the µP when the supply voltage falls below a safe level. The reset output remains asserted for a period after V_CC has risen above the reset threshold level, providing a stable system environment for the µP to initialize. This device is an ideal choice for systems that require a high degree of reliability and operational stability.
