The MAX6328UR31-T is a precision, low-power microprocessor (µP) supervisory circuit from Maxim Integrated. This component is designed to monitor power supplies in µP and digital systems, providing a significant level of system reliability and accuracy required in critical applications. It is ideal for portable and battery-powered equipment due to its low power consumption.

Key Features

• Voltage Monitoring: The MAX6328UR31-T offers precise monitoring of its preset 3.1V voltage threshold, ensuring that the system operates within its voltage parameters. This helps to prevent data corruption and system failures due to out-of-tolerance power supply voltages.
• Reset Output: Upon detecting an out-of-tolerance condition, the device asserts a reset signal to restore the µP system to a known state. The reset output remains asserted for a minimum period (typically 140ms) after the voltage level returns to an acceptable range, providing the system adequate time to stabilize.
• Low Power Consumption: The device is optimized for low power consumption, drawing a quiescent current of typically 1µA, which is essential for battery-powered devices to maximize battery life.
• High Accuracy: The MAX6328UR31-T provides high threshold accuracy (±1.5%) across the entire operating temperature range, ensuring reliable performance under varying conditions.
• Temperature Range: It operates over a broad temperature range of -40°C to +85°C, suitable for a wide range of applications, including harsh environments.
• Small Form Factor: The device is available in a compact SOT-23 package, making it an excellent choice for space-constrained applications.
