The MAX6381XR18D2 is a precision, low-power microprocessor (µP) supervisory circuit designed to monitor voltage levels in a wide range of digital systems. Manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering, this supervisory IC is part of their extensive family of power-supply management devices. The MAX6381XR18D2 is ideal for monitoring 1.8V power supplies, ensuring that systems operate within their specified voltage range and providing a reliable reset signal to the µP during power-up, power-down, and brown-out conditions.

Key Features

• Voltage Threshold: Factory-set reset threshold voltage of 1.8V, suitable for low-voltage applications.
• Reset Timeout: Offers a 210ms (min) reset timeout duration, providing ample time for the system to stabilize before allowing the processor to resume operation.
• Low Power Consumption: With its low supply current of 1.5µA (typ), this device conserves power in battery-operated equipment.
• High Accuracy: Features a ±2% reset threshold accuracy over the entire temperature range, ensuring reliable operation under varying conditions.
• Operating Temperature: Functional across a broad temperature range from -40°C to +125°C, making it suitable for industrial applications.
• Package: Comes in a compact, 3-pin SC70 package, which is ideal for space-constrained applications.
• Push-Pull Output: The active-low RESET output is of the push-pull type, eliminating the need for an external pull-up resistor.
