Working Principles

The LM3881MME/NOPB is a monolithic microprocessor reset circuit that monitors the supply voltage. When the supply voltage drops below the reset threshold, the reset output becomes active, indicating a reset condition. The reset signal remains active until the supply voltage rises above the reset threshold for a specified timeout period. The manual reset input allows an external signal to override the reset condition.

Detailed Application Field Plans

The LM3881MME/NOPB is commonly used in various applications where reliable power-on reset functionality is required. Some of the typical application fields include:

1. Microcontrollers and Microprocessors
2. Embedded Systems
3. Industrial Control Systems
4. Automotive Electronics
5. Battery-Powered Devices
