Working Principles

The TPS3813K33DBVTG4 is a voltage supervisor IC that monitors the supply voltage and generates a reset signal when the voltage falls below a certain threshold. It ensures reliable operation of microcontrollers and other digital systems by preventing them from operating outside the specified voltage range.

The IC continuously compares the supply voltage with a fixed threshold voltage. When the supply voltage drops below the threshold, the reset output is asserted, indicating that the system should be reset. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

The reset timeout period can be programmed using external components, allowing flexibility in defining the duration for which the reset signal remains active after the supply voltage returns to normal. Additionally, the IC provides a manual reset input (MR) that allows the user to assert the reset signal manually, overriding the voltage monitoring function.

Detailed Application Field Plans

The TPS3813K33DBVTG4 is commonly used in various applications where reliable voltage monitoring and system reset functionality are required. Some of the typical application fields include:

1. Microcontroller Systems: Ensures proper initialization and safe operation of microcontrollers by monitoring the supply voltage and generating reset signals when necessary.
2. Industrial Control Systems: Provides voltage supervision and reset capabilities in industrial automation systems, ensuring stable and reliable operation.
3. Automotive Electronics: Monitors the battery voltage in automotive applications, triggering system resets if the voltage falls below a critical level to prevent damage or malfunction.
4. Power Management Systems: Used in power supply units and battery management systems to monitor voltage levels and initiate appropriate actions based on the monitored values.
5. IoT Devices: Enables reliable operation of Internet of Things (IoT) devices by monitoring the power supply and initiating resets if necessary.
