Product Overview: MAX709LEPA+ from Maxim Integrated

The MAX709LEPA+ is a highly reliable and efficient supervisory circuit designed by Maxim Integrated, a renowned leader in the development of integrated circuits. This compact device is engineered to monitor power supplies in microprocessor (µP) systems, providing essential protection and ensuring the stability of the system it serves.

As a power-supply monitor, the MAX709LEPA+ keeps a vigilant eye on the system's voltage levels. It is capable of asserting a reset signal whenever the VCC supply voltage falls below a preset threshold. The reset signal remains active for a minimum of 140ms after VCC rises above the reset threshold, guaranteeing a proper system reset and allowing enough time for the power supply and processor to stabilize.

The device is packaged in an 8-pin µMAX package, which is not only space-efficient but also offers the advantage of reduced power consumption. It operates over a wide voltage range, typically from 4.5V to 5.5V, making it versatile for various applications. Additionally, the MAX709LEPA+ is characterized by its low supply current of 17µA (typical), which is especially beneficial for battery-operated devices where power conservation is a priority.

One of the key features of the MAX709LEPA+ is its ability to provide a debounced manual reset input. This feature allows for a manual system reset without the need for additional external components, simplifying design and reducing overall system costs. The device also offers an active-low reset output, which is compatible with most microprocessor configurations.

Maxim Integrated has ensured that the MAX709LEPA+ is not only robust but also easy to implement in a wide range of applications, including computers, controllers, intelligent instruments, and portable/battery-powered equipment. Its precision voltage monitoring and reset capabilities make it an essential component for maintaining the reliability and performance of electronic systems.

In summary, the MAX709LEPA+ from Maxim Integrated is a versatile, low-power supervisory circuit that provides essential monitoring and protection for microprocessor systems, ensuring that they operate within safe voltage levels and maintain performance integrity.
