MAX707ESA+T - Maxim Integrated Supervisor IC

The MAX707ESA+T from Maxim Integrated is a highly reliable supervisory circuit designed to monitor power supplies in microprocessor (µP) and digital systems. It provides a significant level of protection to your system by ensuring a proper reset operation during power-up, power-down, and brown-out conditions.

This compact and efficient device comes in an 8-pin SOIC package, making it suitable for space-constrained applications. The MAX707ESA+T is designed to maintain system integrity by monitoring the power supply voltage and asserting a reset signal whenever necessary to keep the µP within safe operating conditions.

Key features of the MAX707ESA+T include:

• Voltage Monitoring: The device can monitor a +5V power supply, with a precision voltage sensor capable of detecting under-voltage conditions. This ensures that the system does not operate under harmful voltage levels that could lead to erratic behavior or damage.
• Manual Reset Input: It includes a manual reset input that allows the user to initiate a system reset manually, providing an additional layer of control.
• Watchdog Timer: The integrated watchdog timer ensures that the system does not hang in an unresponsive state by forcing a reset if the µP does not provide a periodic signal within a preset time frame.
• Reset Time Delay: The reset output is guaranteed to remain in the active condition for a minimum of 200ms after the supply voltage has risen above the reset voltage threshold. This ensures the power supply has stabilized before allowing the processor to run.
• Low Power Consumption: The MAX707ESA+T is designed for low power consumption, making it ideal for battery-powered and portable applications.
• Wide Operating Temperature Range: This device can operate over a wide temperature range, making it suitable for use in various environmental conditions.

With its robust feature set, the MAX707ESA+T is an essential component for any system requiring reliable voltage monitoring and reset capabilities. Whether used in computers, controllers, or portable devices, this supervisory circuit from Maxim Integrated helps ensure your system operates safely and effectively.
