Working Principles

The DS1813-10+T&R is designed to monitor the supply voltage level in electronic systems. It compares the input voltage with a pre-set threshold voltage and generates a reset signal when the voltage falls below the threshold. This ensures proper system operation and prevents data corruption or malfunctioning due to insufficient power supply.

The device operates in a low-power mode, consuming only 1.5µA of quiescent current. It continuously monitors the voltage level and provides an active-low push-pull output for driving external circuitry. The threshold voltage can be adjusted according to the specific requirements of the application.

Detailed Application Field Plans

The DS1813-10+T&R is widely used in various electronic systems where precise monitoring of the supply voltage is critical. Some common application fields include:

1. Microcontrollers and microprocessors
2. Embedded systems
3. Industrial automation
4. Power management circuits
5. Battery-powered devices
6. Communication equipment

In these applications, the DS1813-10+T&R ensures reliable operation by providing accurate voltage monitoring and resetting capabilities.
