Descriptions:

The MAX813LEPA is a supervisory circuit designed to monitor power supply voltages in microprocessor-based systems. It ensures proper system operation by generating a reset signal when the supply voltage falls below a specified threshold. It includes a watchdog timer to detect software lockups and a manual reset input for user-initiated resets.

Features:

• Precision Voltage Monitoring: Ensures reliable reset generation when VCC falls below the threshold.
• Watchdog Timer: Detects system lockups and resets the μP if not toggled within the timeout period.
• Manual Reset Input: Allows for external push-button reset control.
• Low Power Consumption: Typically draws 50μA (max) in operating mode.
• Guaranteed Reset Valid Down to VCC = 1V: Ensures proper reset assertion even at very low voltages.
• No External Components Required for Fixed Threshold Versions: Simplifies design.
