Descriptions:

The MAX813LESA is designed to monitor power supply voltages in microprocessor-based systems. It ensures proper system operation by generating a reset signal during power-up, power-down, or brownout conditions. It includes a watchdog timer to detect software lockups and a manual reset input for user-initiated resets.

Features:

• Power Supply Monitoring: Automatically resets the microprocessor during power anomalies.
• Watchdog Timer: Detects software crashes by requiring periodic toggling.
• Manual Reset Input: Allows external push-button reset.
• Power-Fail Comparator: Provides early warning of voltage failure.
• Low Power Consumption: Suitable for battery-powered applications.
• Wide Operating Voltage Range: Supports systems from 1.2V to 5.5V.
• Industrial Temperature Range: Reliable performance in harsh environments.
