Product Overview: Maxim Integrated MAX6385XS44D3

The MAX6385XS44D3 is a high-precision, low-power microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in system monitoring applications. This device is specifically designed to maintain system integrity and prevent data corruption during power failures or unexpected system shutdowns.

Key Features

• Voltage Monitoring: This supervisory circuit monitors the system voltage and ensures that it remains within the acceptable range for reliable operation of the digital system it supervises.
• Reset Output: The MAX6385XS44D3 provides an active-low reset output, which is guaranteed to be in the correct state for VCC down to 1V. This feature is crucial for systems that require a stable reset signal to recover from a power-down or brownout condition.
• Factory-Set Reset Thresholds: The reset thresholds are preset at the factory, eliminating the need for external resistors and adjustments, which simplifies design and enhances reliability.
• Low Power Consumption: Designed with power-conscious systems in mind, this device has an extremely low quiescent current of only 1.1µA, making it suitable for battery-powered and portable applications.
• Manual Reset Input: A manual reset input is provided, allowing the user to trigger a system reset with an external switch or logic signal.
• Temperature Range: The MAX6385XS44D3 operates over an extended temperature range, making it suitable for use in environments with varying temperature conditions.
• Compact Package: Available in a small, surface-mount SOT package, this device occupies minimal board space and is ideal for space-constrained applications.
