Maxim Integrated's MAX813LCUA+ Microprocessor Supervisory Circuit

The MAX813LCUA+ is a highly reliable microprocessor (µP) supervisory circuit designed by Maxim Integrated 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. This supervisory circuit ensures that your system operates effectively by providing crucial functions such as power-on reset control, watchdog timing, and manual reset capability.

Key Features

• Power-On Reset: The MAX813LCUA+ generates a reset pulse whenever the VCC supply voltage falls below the reset threshold, ensuring that the µP starts up in a known state every time.
• Watchdog Timer: With its built-in watchdog timer, this device monitors system operation and resets the µP in case of system malfunction or software lock-up.
• Manual Reset: An additional feature is the manual reset input that allows for a system reset to be initiated with an external pushbutton or logic signal.
• Low Power Consumption: The device is designed for low power consumption, which is critical for battery-operated and power-sensitive systems.
• Reset Threshold Options: The MAX813LCUA+ is available with several reset voltage threshold options to accommodate different system requirements.
• Compact Package: It comes in an 8-pin µMAX package, which is ideal for space-constrained applications.

Applications

The MAX813LCUA+ is suitable for a wide range of applications that require reliable system monitoring and reset functions. It is commonly used in:

• Computers and Controllers
• Embedded Systems
