Product Overview: MAX705CSE - Maxim Integrated

The MAX705CSE is a sophisticated microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor the 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 µP's power supply remains within acceptable limits, with a precision voltage monitor for +5V power supplies.
• Reset Output: The MAX705CSE offers a reset output during power-up, power-down, and brownout conditions. The reset signal remains operational with VCC as low as 1V.
• Backup Battery Switchover: An added feature is the backup battery switchover that does not require a diode.
• Watchdog Timer: A watchdog timer is built in to keep the µP in check. If the µP fails to strobe within a preset timeout period, the MAX705CSE will assert a system reset.
• Manual Reset: A manual reset feature allows for a reset to be triggered with a simple push of a button.

Applications

The MAX705CSE is ideal for use in a wide range of applications, including:

• Computers and Controllers
• Intelligent Instruments
• Automotive Systems
• Critical µP Power Monitoring

Package and Quality

Enclosed in a 16-pin narrow SO package, the MAX705CSE is designed to be compact and versatile for integration into various system designs. Maxim Integrated ensures quality and reliability, and the MAX705CSE is no exception, meeting the company's high standards for performance.

Conclusion

In summary, the MAX705CSE from Maxim Integrated is a robust µP supervisory circuit that provides essential protection features for digital systems. Its ability to monitor voltage levels, provide a reliable reset signal, and integrate a watchdog timer makes it an invaluable component for ensuring the stable operation of electronic systems.
