ON Semiconductor MAX708SESA-TG Microprocessor Supervisory Circuit

The MAX708SESA-TG from ON Semiconductor is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of protection to your system by ensuring that the µP boots up in a known state and by preventing code execution errors during power-up, power-down, or brown-out conditions.

This compact device is housed in an 8-pin SOIC package, offering a space-saving solution for a variety of applications, including computers, controllers, intelligent instruments, and critical µP power monitoring. The MAX708SESA-TG is a versatile component that is suitable for systems that require a watchdog timer, manual reset capability, and a precise reset threshold voltage.

Key Features:

• Reset Threshold Voltage: The device features a factory-set reset threshold voltage that helps in maintaining the proper operation of the µP by monitoring the VCC for under-voltage conditions.
• Watchdog Timer: A built-in watchdog timer ensures that the µP remains in a safe state by monitoring the system for software faults and providing a system reset if necessary.
• Manual Reset Input: The manual reset input allows for a system reset to be triggered with an external push-button or logic signal, providing an additional layer of control.
• Reset Output: The active-low RESET output remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, ensuring the system has sufficient time to stabilize.
• Power Supply Tolerance: It can tolerate a wide power supply range, making it suitable for various digital systems.
• Low Power Consumption: The device is designed for low power consumption, which is critical for battery-powered applications.
• Temperature Range: The MAX708SESA-TG operates over the extended industrial temperature range, ensuring reliability under varying environmental conditions.

With its robust set of features, the MAX708SESA-TG supervisory circuit from ON Semiconductor is an essential component for ensuring system stability and reliability. Whether it's being used in complex digital systems or simple microcontroller applications, this device provides the necessary oversight to keep your system running smoothly.
