Working Principles

The TPS3824-25DBVR operates by continuously monitoring the power supply voltage. When the voltage falls below the preset threshold (2.5V), the reset output is activated, indicating a power failure or unstable voltage condition. The reset signal remains active until the voltage rises above the threshold again. The manual reset pin allows for an external reset signal to override the internal monitoring.

The TPS3824-25DBVR finds applications in various electronic systems where reliable power supply monitoring is crucial. Some potential application fields include:

1. Microcontrollers and microprocessors
2. Industrial control systems
3. Automotive electronics
4. Medical devices
5. Communication equipment
6. Power management systems
