The MAX6328UR22 from Maxim Integrated is a highly precise, low-power microprocessor (µP) supervisory circuit designed to maintain system integrity during power failures or unexpected events. This component is ideal for portable and battery-powered equipment due to its low power consumption and compact SC70/SOT package.

Key Features

• Voltage Monitoring: The MAX6328UR22 monitors the system voltage and keeps the µP in reset until that voltage reaches the factory-set reset threshold of 2.2V. This ensures a stable system operation during power-up, power-down, and brown-out conditions.
• Low Power Consumption: With a quiescent current of only 1µA, it is optimized for battery-powered devices where power efficiency is crucial.
• Manual Reset Input: This feature allows for a manual system reset, providing an additional layer of system control and security.
• Reset Timeout: After the supply voltage exceeds the reset threshold, the MAX6328UR22 keeps the µP in reset for a period of 140ms (min), allowing the system power supply to stabilize.
• Compact Package: Available in a small SC70 or SOT package, this device is suitable for space-constrained applications.
• Temperature Range: The operating temperature range of -40°C to +85°C ensures reliable performance across various environmental conditions.
