Maxim Integrated's MAX708SCUA+T Microprocessor Supervisory Circuit

The MAX708SCUA+T is a highly reliable and robust microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in system monitoring applications.

Key Features

• Supply Voltage Monitoring: The device ensures that the system's supply voltage levels are within acceptable thresholds, providing a reset output during power-up, power-down, and brown-out conditions.
• Reset Timeout: It offers a precision timing circuit with a fixed reset timeout period of 200ms, ensuring the µP is held in the reset state long enough to stabilize.
• Manual Reset Capability: A manual reset input allows for a very low power pushbutton reset feature, enabling users to manually initiate a system reset.
• Low Power Consumption: With its low supply current draw, the MAX708SCUA+T is ideal for power-sensitive applications, extending battery life in portable devices.
• Watchdog Timer: An integrated watchdog timer provides an additional layer of system reliability by monitoring the system for software lock-up conditions.
• Versatile Operating Voltage: The device operates over a wide voltage range, accommodating various system requirements.
• Compact Package: The MAX708SCUA+T comes in an 8-pin µMAX package, ideal for space-constrained applications.
