Product Overview: MAX6394US317D3+T

The MAX6394US317D3+T is a robust, low-power microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a renowned leader in the development of integrated circuits. This device is engineered to provide precision monitoring of power supplies in µP and digital systems, ensuring reliable system operation by monitoring the system voltage and asserting a reset if a fault condition is detected.

Key Features

• Voltage Monitoring: The MAX6394US317D3+T supervisory circuit monitors a fixed factory-set threshold voltage of 3.17V, making it suitable for 3.3V systems. It provides an active-low reset output which remains asserted until the system voltage stabilizes above the threshold.
• Power-On Reset Delay: The device includes an internally set power-on reset delay (typically 140ms), which provides a stable reset signal to the µP during power-up, power-down, or brownout conditions.
• Low Quiescent Current: Designed for power-sensitive applications, the MAX6394US317D3+T features a low quiescent current of typically 1.6µA, which helps in reducing the overall power consumption of the system.
• Manual Reset Input: An additional feature of this supervisory circuit is the manual reset input, which allows for an external signal to trigger the reset, providing a means for system diagnostics or a controlled system restart.
• High Accuracy: This device offers high threshold voltage accuracy (±1.5%) across the entire operating temperature range of -40°C to +125°C, ensuring reliable monitoring under varying conditions.
• Compact Package: The MAX6394US317D3+T comes in a compact, 4-pin SOT143 package, which is ideal for space-constrained applications.

Applications

The MAX6394US317D3+T is versatile and can be used in a wide array of applications where system reliability and power management are crucial. It is commonly found in portable/battery-powered devices, consumer electronics, embedded systems, and industrial controllers.

By integrating the MAX6394US317D3+T into your system, you can ensure that your µP and other digital systems are protected against unpredictable voltage fluctuations, thereby enhancing system stability and reliability.
