Maxim Integrated MAX6375UR25+T Voltage Supervisory IC

The MAX6375UR25+T from Maxim Integrated is a precision, 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 monitoring 2.5V power supplies.

This supervisory IC is ideal for portable and battery-powered equipment due to its low power consumption and small size. The MAX6375UR25+T asserts a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. This ensures the proper reset of a microprocessor during power-up, power-down, or brownout conditions.

Key features of the MAX6375UR25+T include:

• Factory-Set Reset Thresholds: This device comes with a preset VCC threshold of 2.5V, which is tailored for specific applications, thereby reducing the complexity of design.
• Low Supply Current: With its low supply current of 1.5µA, this device is highly efficient for power-sensitive applications.
• Guaranteed Reset Valid to VCC = 1V: The reset output is guaranteed to remain in the correct state even when VCC drops to as low as 1V, ensuring reliable operation under all conditions.
• Power Supply Transient Immunity: The MAX6375UR25+T is designed to ignore fast transients on the VCC line, which helps to prevent false resets from occurring.
• Compact SOT23 Packaging: This device is available in a small SOT23 package, which is perfect for space-constrained applications.

Additionally, the MAX6375UR25+T is fully specified over the -40°C to +125°C extended temperature range, making it suitable for industrial applications where temperature extremes are common.

In summary, the MAX6375UR25+T voltage supervisory IC from Maxim Integrated is a reliable, efficient solution for monitoring 2.5V power supplies in a variety of digital systems. Its combination of low power consumption, small form factor, and robust feature set ensures stable and secure operations for microprocessors in diverse applications.
