• Lack of additional features such as hysteresis or adjustable threshold voltage may restrict its use in specific scenarios.

Working Principles

MIC803-26D2VC3-TR operates based on a voltage comparator circuit. It compares the input voltage with the preset threshold voltage. When the input voltage drops below the threshold, the comparator triggers the reset signal, indicating the need for a system reset. The reset signal remains active for the specified timeout period, allowing the system to stabilize before resuming normal operation.

Detailed Application Field Plans

MIC803-26D2VC3-TR finds applications in various electronic devices where voltage monitoring and reset functions are critical. Some potential application fields include:

1. Microcontrollers: Ensures proper functioning by monitoring the supply voltage and initiating a reset if necessary.
2. Power Management Systems: Protects sensitive components from voltage fluctuations and prevents damage.
3. Battery-Powered Devices: Monitors battery voltage to prevent over-discharge and prolong battery life.
4. Industrial Control Systems: Provides reliable voltage monitoring for stable operation of control circuits.
