The MAX6328XR22+T from Maxim Integrated is a highly precise, low-power microprocessor (µP) supervisory circuit designed 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 system's voltage levels are stable and within acceptable limits, with a factory-set reset threshold voltage of 2.2V, making it ideal for 2.2V-powered systems.
• Low Power Consumption: With a quiescent current of only 1µA, the MAX6328XR22+T is optimized for battery-powered and energy-efficient applications.
• Reset Output: It features an active-low reset output, which provides a reset signal to the microprocessor during power-up, power-down, and brown-out conditions.
• High Accuracy: This supervisory circuit offers a high reset threshold accuracy of ±1.5% at room temperature and ±2.1% over the full temperature range of -40°C to +125°C.
• Immune to Short VDD Transients: Fast transients on the VDD line are filtered, preventing false resets and ensuring stable operation of the connected microprocessor.
• Compact Package: The MAX6328XR22+T comes in a small, surface-mount SOT-23 package, which is ideal for space-constrained applications.
