The MAX6328-22D is a precision, low-power, low-voltage microprocessor (µP) supervisory circuit designed by NXP Semiconductors 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 with a 2.2V power supply voltage.

Key Features

• Voltage Monitoring: This device ensures that the µP and its peripherals are reset properly during power-up, power-down, and brown-out conditions. The MAX6328-22D monitors the supply voltage and keeps the µP in reset until that voltage reaches the factory-trimmed reset threshold of 2.2V.
• Low Power Consumption: With its low supply current of 1µA (typical), the MAX6328-22D is ideal for use in portable equipment where extending battery life is a priority.
• Manual Reset: A manual reset input allows the user to initiate a system reset, providing additional system reliability.
• Reset Timeout: After the supply voltage rises above the reset threshold, the reset output remains asserted for a reset timeout period to ensure the system microprocessor starts up properly.
• Temperature Range: The device operates over an extended temperature range, making it suitable for a variety of environments and applications.
• Package Options: The MAX6328-22D is available in a small SOT-23 package, providing a compact solution for space-constrained applications.

Applications

The MAX6328-22D is versatile and can be used in a broad range of applications, including:

• Portable/Battery-Powered Equipment
• Embedded Systems
• Microprocessor/Microcontroller Systems
• Data Storage Equipment
• Industrial/Commercial Systems

With its combination of features, the MAX6328-22D from NXP provides an efficient and reliable solution for system power supply monitoring and is an essential component for enhancing system stability and performance.
