The MAX982EPA+ is a high-precision, low-power 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 systems with a single +5V power supply.

Key Features

• Voltage Monitoring: This device keeps a close watch on the system's power supply voltage levels, ensuring that they remain within acceptable thresholds for reliable operation.
• Reset Output: In the event of a dip below the preset threshold, the MAX982EPA+ generates a reset signal, which holds the µP in reset for a minimum of 140ms after VCC has risen above the reset threshold. This ensures that the µP restarts only when the power supply is stable.
• Manual Reset: A manual reset feature allows the user to initiate a system reset through an external button or signal, providing additional system control.
• Low Power Consumption: With its low power requirements, the device helps to conserve energy, making it ideal for power-sensitive applications.
• Compact Package: The MAX982EPA+ comes in an 8-pin DIP package, which is suitable for space-constrained applications.
