The MAX706ASESA+ from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed 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 with +5V-powered circuits.

This supervisory circuit significantly improves system reliability and accuracy compared to separate ICs or discrete components. The MAX706ASESA+ offers several key features that make it ideal for a variety of applications, including computers, controllers, intelligent instruments, and critical µP power monitoring.

Key Features:

• Supply Voltage Monitoring: The device ensures that the microprocessor is fully reset during power-up, power-down, and brownout conditions. It keeps the µP in the reset condition until the supply voltage reaches a stable condition again.
• Manual Reset Input: This feature allows a manual reset to be initiated, providing additional system control flexibility.
• Watchdog Timer: A watchdog timer is built-in to monitor the microprocessor, ensuring it operates within the expected parameters and sequences.
• Power-Fail Input: The MAX706ASESA+ includes a power-fail input that provides an early warning of impending power failure, allowing the system to take appropriate action.
• Low Power Consumption: The device operates with a low quiescent current, making it suitable for power-sensitive applications.
• Compact Package: Available in an 8-pin SO package, the MAX706ASESA+ is designed for space-constrained applications.

Applications:

The MAX706ASESA+ is versatile and can be used in various applications where reliable system monitoring is crucial. It is particularly well-suited for:

• Portable/Battery-Powered Equipment
