The MAX793TEPE+ is a high-performance, low-power microprocessor (μP) supervisory circuit designed and manufactured by Maxim Integrated. This device is engineered to provide precision monitoring of power supplies in μP and digital systems. It ensures that the system operates reliably by providing a reset signal to the μP during power-up, power-down, and brown-out conditions.

Key Features

• Voltage Monitoring: The MAX793TEPE+ monitors the power supply voltage and keeps the μP in reset until that voltage reaches a stable and precise factory-set threshold. This feature helps prevent erratic system behavior due to insufficient power.
• Manual Reset Input: A dedicated manual reset input allows for an external trigger to reset the system, providing additional control to the user for system maintenance or debugging.
• Low Power Consumption: With its low power design, the MAX793TEPE+ is suitable for battery-powered applications, contributing to the overall energy efficiency of the system.
• Watchdog Timer: The integrated watchdog timer ensures the system remains operational by resetting the μP if it fails to strobe within a preset timeout period, indicating a potential system fault or software freeze.

Applications

The MAX793TEPE+ is versatile and can be used in a variety of applications where reliable system operation is crucial. These include:

• Computers and Servers
• Embedded Systems
• Industrial Controllers
• Portable/Battery-Powered Equipment

Technical Specifications

The device comes in a 16-pin PDIP (Plastic Dual In-line Package) and is characterized for operation over the full industrial temperature range (-40°C to +85°C). It features a reset output stage with the option for either push-pull or open-drain configuration, which allows flexibility in interfacing with different μP systems. The MAX793TEPE+ is designed with a supply voltage range typically from 4.5V to 5.5V, making it suitable for 5V powered systems.
