Product Overview: MAX708EPA from Maxim Integrated

The MAX708EPA is a sophisticated microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability and accuracy required for modern electronic applications. This device is particularly well-suited for use in systems that require a high degree of operational stability and protection against power supply anomalies.

Featuring a combination of functions such as reset output during power-up, power-down, and brownout conditions, the MAX708EPA ensures that the µP is reset to a known state during such events. This is critical in preventing system errors and data corruption that may occur due to unpredictable power supply issues. The reset signal provided by the MAX708EPA is guaranteed to be valid down to V_CC = 1V, making it reliable even in low-voltage conditions.

This device is particularly easy to integrate into a system, with options for both push-pull and open-drain reset outputs, which are active-low. The MAX708EPA includes a debounced manual reset input, allowing for a manual reset trigger, which can be a valuable feature during system maintenance or troubleshooting. Additionally, it has a 200ms reset timeout period, ensuring that the system has ample time to stabilize before resuming operation after a reset event.

The MAX708EPA comes in a compact 8-pin DIP package, making it convenient for space-constrained applications. It operates over a wide temperature range of -40°C to +85°C, which is suitable for industrial environments and other applications with extreme temperature requirements. Furthermore, this supervisory circuit has a low supply current of only 17µA (typical), making it an energy-efficient choice for portable and battery-powered devices.

Overall, the MAX708EPA from Maxim Integrated is a reliable and versatile solution for system monitoring and control. Its integration into electronic systems helps ensure that they operate consistently and effectively, even in the face of power supply uncertainties.
