Working Principles

The TPS3823-25DBVRG4 operates by continuously monitoring the supply voltage. When the voltage drops below the preset threshold (2.5V), the device generates a reset signal, indicating a power-on reset condition. Additionally, it includes a watchdog timer that must be periodically refreshed to prevent system lock-up. If the watchdog timer is not refreshed within the specified timeout period (1.6s), a reset signal is generated.

Detailed Application Field Plans

The TPS3823-25DBVRG4 finds application in various electronic systems where stable voltage levels are critical. Some of the common application fields include:

1. Microcontrollers: Ensuring reliable operation by monitoring the supply voltage and initiating a reset if necessary.
2. Industrial Control Systems: Preventing malfunctions due to voltage fluctuations and ensuring uninterrupted operation.
3. Automotive Electronics: Monitoring the battery voltage to prevent damage to sensitive components and ensure proper functioning.
4. Communication Systems: Maintaining stable voltage levels to avoid data loss or system failures.
5. Medical Devices: Ensuring the safety and reliability of medical equipment by monitoring voltage levels.
