The MAX807LEPE is a sophisticated microprocessor (µP) supervisory circuit designed by Maxim Integrated to provide a reliable solution for system monitoring and power management. This high-performance component is engineered to maintain the integrity of digital systems by monitoring the power supply and microprocessor activity.

Key Features

• Power Supply Monitoring: The device ensures that the system's power supply remains within operational thresholds, providing a reset output during power-up, power-down, and brown-out conditions. This feature helps to prevent system errors and data corruption caused by inadequate power levels.
• Microprocessor Reset: It generates a reset signal to the µP during power failures, keeping the processor in reset until conditions stabilize. This reset signal is maintained for a minimum of 140ms after the supply voltage exceeds the reset threshold, ensuring a proper system restart.
• Manual Reset Capability: A manual reset input allows for an external trigger to initiate a system reset, providing additional control to service personnel or system users.
• Watchdog Timer: The integrated watchdog timer monitors system operation. If the µP fails to provide a periodic signal, the MAX807LEPE assumes a system fault and issues a reset, aiding in the recovery from software lock-up conditions.
• Debounced Manual Reset Input: The manual reset input is debounced, which ensures that only clean transitions affect the reset output, preventing false triggering due to noise or contact bounce.

Applications

The MAX807LEPE is ideal for use in a variety of applications where reliable system monitoring is critical. It's commonly found in:

• Computers and servers
• Embedded systems
• Communication equipment
• Portable/battery-powered devices

Product Specifications

The device is offered in a 16-pin PDIP (Plastic Dual In-line Package) encapsulation, ensuring easy integration into a wide range of system designs. The MAX807LEPE operates over a wide temperature range, making it suitable for various environmental conditions. It is designed to interface directly with a 5V power supply, a common voltage in digital systems, providing broad compatibility with industry-standard µPs and digital logic.
