Working Principles

The DS1813-5 is a monolithic CMOS IC that provides precise voltage monitoring and reset generation. It continuously monitors the supply voltage and asserts the reset output when the voltage falls below the specified threshold. The reset output remains active until the supply voltage rises above the threshold or a manual reset input is triggered.

Detailed Application Field Plans

The DS1813-5 finds applications in various fields, including:

1. Embedded Systems: Ensures reliable operation by monitoring power supply voltage and initiating system resets if necessary.
2. Industrial Control: Provides voltage supervision to critical components, preventing malfunctions due to unstable power supply.
3. Automotive Electronics: Monitors battery voltage to prevent damage caused by under-voltage conditions and initiates system resets if required.
4. Consumer Electronics: Enhances system reliability by monitoring power supply voltage and resetting the system in case of voltage fluctuations.
