Product Overview: MAX817LESA+ from Maxim Integrated

The MAX817LESA+ is a high-performance microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability and accuracy required for critical applications. This compact device offers a range of features that make it an essential component in enhancing system integrity.

Key Features

• Precision Monitoring: The MAX817LESA+ offers precision monitoring of +5V, +3.3V, and adjustable voltage power supplies, ensuring that the system operates within safe voltage levels.
• Reset Output: It comes with an active-low reset output that remains asserted for a minimum of 140ms after VCC returns to an in-tolerance condition, providing ample time for the system to stabilize upon power-up.
• Manual Reset Input: A manual reset input feature allows for a system reset to be triggered with an external switch or logic signal, offering additional control to the system operators.
• Low Power Consumption: Designed for power-sensitive applications, the MAX817LESA+ has a low quiescent current draw, thereby reducing the overall power consumption of the system.
• Watchdog Timer: The integrated watchdog timer ensures that the system software is running correctly by resetting the µP if it fails to strobe within a preset timeout period.
• Versatile Voltage Monitoring: The device is capable of monitoring multiple voltages, which makes it versatile for various applications that require different voltage thresholds.
