Product Overview: MAX6389XS16D3+T by Maxim Integrated

The MAX6389XS16D3+T is a robust, precision 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 particularly suitable for monitoring 1.8V to 5V power supplies and can assert a reset signal whenever the VCC supply voltage drops below its preset threshold, ensuring that the μP resets cleanly during power-up, power-down, and brown-out conditions.

Key Features

• Voltage Monitoring: The MAX6389XS16D3+T monitors the system voltage and actively manages the reset function for processors, ensuring the system starts in a known state.
• Programmable Reset Timeout: It offers a programmable reset timeout delay, which allows designers to set the duration that the reset signal is maintained.
• Low Power Consumption: With its low power consumption, this supervisory circuit is ideal for portable and battery-operated equipment.
• High Accuracy: The reset voltage threshold is factory-set with high accuracy, which helps to avoid any unintentional resets due to fluctuating power supply.
• Operating Temperature Range: It operates over a wide temperature range, making it suitable for various industrial and consumer applications.
• Surface-Mount Package: Available in a small, surface-mount package, the MAX6389XS16D3+T is designed for space-constrained applications.
