The MAX706SCUA+ from Maxim Integrated is a compact, highly-reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in conjunction with +5V-powered circuits.

Key Features

• Voltage Monitoring: This device ensures that the microprocessor is reset to a known state during power-up, power-down, and brownout conditions. It monitors the power supply voltage and maintains the reset output until the system voltage stabilizes above the reset threshold.
• Manual Reset: A manual reset feature allows for a reset to be triggered with an external switch or logic signal, providing additional system control.
• Low Power Consumption: The MAX706SCUA+ is designed for low power consumption, making it suitable for battery-operated applications.
• Integrated Watchdog Timer: The built-in watchdog timer ensures that the µP does not hang in an indefinite loop, enhancing system reliability.
