The MAX708RESA-T from ON Semiconductor is a compact, highly reliable supervisory circuit designed to monitor power supply and system health in microprocessor systems. It provides essential functions such as power-on reset control, watchdog timer, and manual reset capability, ensuring that systems operate smoothly and reliably.

Key Features

• Reset Timeout: The device offers a preset reset timeout of 200ms, ensuring that the system has sufficient time to stabilize before normal operation resumes.
• Watchdog Timer: A 1.6s watchdog timer is integrated, which helps to detect and recover from system malfunctions. If the system fails to provide a regular kicking signal within this period, the device will initiate a system reset.
• Manual Reset: A manual reset input allows for an external signal to trigger a system reset, providing an additional layer of control for system management.
• Low Power Consumption: Designed for power-sensitive applications, this supervisory circuit operates with low power consumption, making it ideal for battery-operated systems.
• Voltage Monitoring: The device monitors the system voltage and provides a reset output during power-up, power-down, and brown-out conditions.
• High Accuracy: It features high threshold accuracy (±1.5%) for reliable monitoring and reset initiation.

Applications

The MAX708RESA-T is suitable for a wide range of applications where system integrity is crucial. It is commonly used in:

• Microprocessor and microcontroller systems
• Computers and embedded systems
• Portable/battery-powered equipment
• Industrial controllers
• Automotive systems
