Disadvantages: - Limited reset timeout period - Single-channel voltage supervision
Working Principles
The MIC812TU TR operates by continuously monitoring the supply voltage. When the voltage falls below the selected threshold voltage, the reset output is activated, indicating a power failure or voltage drop. The reset output remains active until the supply voltage rises above the threshold and the reset timeout period elapses.
Detailed Application Field Plans
The MIC812TU TR is commonly used in various applications where reliable voltage supervision is required. Some of the typical application fields include:
- Microcontrollers: Ensuring proper system initialization and preventing data corruption during power fluctuations.
- Embedded Systems: Providing a reset signal to restart the system after a power failure.
