Working Principles

MIC803-26D3VM3-TR operates based on a voltage comparator circuit. It compares the supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the reset output is activated. The reset signal remains active until the supply voltage rises above the threshold or the reset timeout period elapses.

Detailed Application Field Plans

MIC803-26D3VM3-TR finds application in various electronic systems where voltage monitoring and reset functions are critical. Some specific application fields include:

1. Microcontrollers: Ensures proper reset and initialization of microcontrollers during power-up or voltage fluctuations.
2. Embedded Systems: Provides reliable voltage monitoring for stable operation of embedded systems.
3. Power Management: Protects sensitive components by generating reset signals when the supply voltage falls outside the acceptable range.
4. Industrial Control Systems: Prevents data corruption and system malfunctions by resetting control systems during voltage disturbances.
