• Limited number of threshold voltage options may not cater to all specific voltage monitoring requirements.
• Manual reset input may require additional external components for proper functionality in certain applications.

Working Principles

The MAX6313UK25D3-T operates by continuously monitoring the supply voltage connected to the VCC pin. When the voltage falls below the selected threshold voltage (set using the TH pin), the device generates a reset signal on the RESET pin. This signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Application Field Plans

The MAX6313UK25D3-T is widely used in various electronic systems where reliable voltage monitoring is crucial. Some application fields include:

1. Battery-Powered Devices: Ensures safe operation by providing a reset signal when the battery voltage drops below a critical level.
2. Microcontroller Systems: Protects against voltage fluctuations, preventing erratic behavior or data corruption.
3. Industrial Control Systems: Monitors power supply integrity, ensuring stable operation of critical equipment.
4. Automotive Electronics: Guards against voltage dips or spikes, enhancing the reliability of automotive systems.
