The MAX6326-22D is a precision voltage microprocessor (μP) supervisory circuit from NXP Semiconductors, designed to maintain system integrity through monitoring power supplies. It's a key component in applications requiring a high degree of reliability and accuracy in voltage monitoring, such as industrial systems, medical devices, and portable electronics.

Key Features

• Voltage Monitoring: The MAX6326-22D provides a precise supervisory function for a 2.2V power supply, ensuring that the system voltage remains within operational thresholds.
• Reset Output: This component features an active-low reset output, which holds the microprocessor in reset until the system voltage stabilizes. The reset signal remains asserted for a minimum of 140ms after the voltage exceeds the reset threshold, allowing the power supply and μP to stabilize.
• Low Power Consumption: With a low supply current of typically 1.2μA, the MAX6326-22D is ideal for battery-operated equipment, contributing to extended battery life and efficiency.
• High Accuracy: The reset threshold accuracy of ±1.5% ensures reliable monitoring and system protection over the entire temperature range.
• Temperature Range: It operates over an extended temperature range of -40°C to +125°C, making it suitable for use in harsh environments and diverse applications.

Applications

The MAX6326-22D is versatile and can be implemented across a wide range of applications. It is particularly useful in systems where accurate voltage monitoring is critical to the safety and functionality of the device, such as:

• Portable/Battery-Powered Devices
• Embedded Systems
• Data Storage Systems
• Medical Monitoring Equipment
• Industrial Control Systems
