Maxim Integrated's MAX813LESA+ Microprocessor Supervisory Circuit

The MAX813LESA+ from Maxim Integrated is a highly reliable and compact microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in battery-powered applications such as computers, controllers, and intelligent instruments.

Key Features

• Power Supply Monitoring: The device ensures that the microprocessor is fully reset during power-up, power-down, and brown-out conditions. It monitors the power supply voltage and keeps the microprocessor in the reset state until the power supply reaches a stable and safe level for operation.
• Manual Reset Input: An additional feature is the manual reset input, which provides a direct and easy way for the user to initiate a system reset with an external pushbutton or logic signal.
• Watchdog Timer: To prevent system failures, the MAX813LESA+ includes a watchdog timer that resets the microprocessor if it fails to strobe within a preset timeout period.
• Backup Battery Switchover: In the event of a power failure, the device automatically switches to a backup battery to maintain power supply integrity.
• Compact 8-Pin SO Package: The MAX813LESA+ is available in a space-saving 8-pin SO package, which is ideal for systems where space is at a premium.

Applications

With its versatile features, the MAX813LESA+ is suitable for a wide range of applications, including:

• Computers and Servers
• Embedded Systems
• Portable/Battery-Powered Equipment
• Intelligent Instruments
• Industrial Controllers

The MAX813LESA+ provides an efficient and reliable solution for system monitoring and is an essential component for enhancing system integrity. Its integration into your design will ensure that your microprocessor-based systems operate smoothly and consistently, even in the face of power instability.
