The MAX813LCPA is a highly integrated supervisory circuit designed by Maxim Integrated to monitor power supplies in microprocessor (µP) and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in battery-powered systems.

This supervisory circuit is designed to maintain system integrity through a variety of features. It includes a precision voltage monitor with a 4.65V threshold, a manual reset input, and a watchdog timer. The reset output is guaranteed to remain in the active condition for a minimum of 140ms after VCC has risen above the reset threshold level, ensuring that the µP has ample time to stabilize.

The MAX813LCPA comes in an 8-pin DIP package and operates over a wide temperature range, making it suitable for diverse applications. Its low power consumption makes it an ideal choice for portable and battery-powered electronics. The device's watchdog timer helps to ensure that if a system becomes unresponsive, it can be reset in a controlled manner, thus enhancing the overall system reliability.

Key features of the MAX813LCPA include:

• Precision voltage monitor with 4.65V threshold
• Manual reset input for additional system control
• Watchdog timer for system reliability enhancement
• Minimum 140ms reset output timeout
• Wide operating temperature range
• Low power consumption for battery efficiency
• 8-pin DIP package for easy integration

Applications for the MAX813LCPA supervisory circuit extend across various sectors, including computers, controllers, intelligent instruments, critical µP power monitoring, and portable/battery-powered equipment. Its reliability and ease of use make it a go-to component for designers looking to ensure system stability and integrity.
