Maxim Integrated MAX791CPE - Voltage Monitor

The MAX791CPE from Maxim Integrated is a precision voltage monitor designed to ensure the reliable operation of microprocessors (µPs) and other voltage-sensitive devices. It is a crucial component for systems that require a stable and accurate power supply to maintain functionality and prevent data corruption.

Key Features:

• Voltage Monitoring: The device monitors its own power supply voltage as well as a second voltage. It is capable of monitoring a +5V power supply and a second power supply as low as 1.25V.
• Reset Output: It provides a reset output during power-up, power-down, and brownout conditions. The reset signal remains valid with VCC as low as 1V.
• High Accuracy: The MAX791CPE features a precision voltage threshold and a tight reset threshold accuracy of ±1.5% over the entire temperature range.
• Low Power Consumption: Designed for energy efficiency, it has a low supply current of 40µA, which is ideal for power-sensitive applications.
• Manual Reset Input: It includes a manual reset input that allows a pushbutton or external logic to initiate system reset.
• Package Type: The device is offered in an 8-pin DIP (Dual In-line Package) and SO (Small Outline) packages, providing flexibility for various PCB layouts.

Applications:

The MAX791CPE is suitable for a wide array of applications where precise voltage monitoring is critical. These include:

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

With its high accuracy and low power consumption, the Maxim Integrated MAX791CPE voltage monitor is an excellent choice for designers looking to enhance system reliability and protect their digital systems from the dangers of unpredictable power supply conditions.
