Maxim Integrated MAX791MJE/883 Precision Voltage Monitor

The MAX791MJE/883 is a highly reliable, precision voltage monitor from Maxim Integrated, designed to ensure the stability and functionality of microprocessor systems. This integrated circuit is part of Maxim's heritage of robust and precision-engineered components, tailored to meet the stringent requirements of military and aerospace applications. The device is characterized for operation over the full military temperature range of -55°C to +125°C, making it an ideal choice for mission-critical environments where performance and durability are paramount.

One of the key features of the MAX791MJE/883 is its ability to monitor power supplies in microprocessor systems. It provides a reset output during power-up, power-down, and brown-out conditions. On power-up, the reset signal is asserted when the supply voltage reaches 1V. After the supply voltage exceeds the reset threshold, the reset signal remains asserted for a minimum of 140ms, ensuring the system has sufficient time to stabilize.

The device has a preset threshold voltage of 4.65V, which is factory-trimmed for high accuracy. This feature is critical for systems that require consistent and predictable monitoring of the power supply to prevent data corruption and ensure reliable operation. Additionally, the MAX791MJE/883 includes a debounced manual reset input, which allows for a manual assertion of the reset signal, providing an extra level of control to the system operator.

Engineered with a low supply current, the MAX791MJE/883 is an energy-efficient solution that contributes to the overall power management of the system it is integrated into. Its compact 16-pin CERDIP package makes it suitable for space-constrained applications, while its military-grade design ensures it can withstand the harsh conditions often encountered in defense and aerospace operations.

In summary, the MAX791MJE/883 precision voltage monitor is a testament to Maxim Integrated's commitment to delivering high-quality, reliable components for advanced electronic systems. Its precision voltage monitoring, robust temperature range, and additional features make it an essential component for any design requiring stringent voltage supervision.
