The MAX791EPE is a high-quality voltage supervisor integrated circuit (IC) designed and manufactured by Maxim Integrated, a renowned leader in the development of innovative analog and mixed-signal products. This IC is engineered to monitor power supplies in microprocessor (µP) systems, providing a precise, low-power method of monitoring system voltages.

Key Features

• Voltage Monitoring: The device offers a precise voltage monitoring system that ensures the stability and reliability of the µP power supply, helping to prevent data corruption and system failures.
• Power-on Reset: It provides a power-on reset feature which generates a reset signal whenever the monitored voltage falls below the factory-set reset threshold, thereby initializing the µP safely during power-up, power-down, and brown-out conditions.
• Reset Timeout: The MAX791EPE includes an adjustable reset timeout period which can be set by the user according to the specific needs of the application, offering flexibility and control over the reset function.
• Low Power Consumption: This IC is designed for low power consumption, making it ideal for use in portable and battery-powered applications where power efficiency is critical.
• Package Type: It comes in an 8-pin plastic DIP (Dual In-line Package) encapsulation, which is suitable for through-hole mounting on printed circuit boards (PCBs).
