Functional Features

1. Voltage Monitoring: The TPS3898ADRYR continuously monitors the input voltage and provides a reset signal when it falls below or rises above a predefined threshold.
2. Power-On Reset: It generates a reset signal during power-up, ensuring proper initialization of the system.
3. Watchdog Timer: The IC includes a watchdog timer that detects system malfunctions and generates a reset signal if the system fails to provide a periodic input within a specified time.

Advantages

• Low power consumption extends battery life in portable devices.
• Wide operating voltage range allows compatibility with various systems.
• High accuracy ensures reliable voltage monitoring.
• Small package size saves board space in compact designs.
• Robust design enables operation in harsh environmental conditions.

Disadvantages

• Limited number of threshold voltage options may not cater to all specific requirements.
• Lack of additional features such as adjustable delay time or hysteresis limits customization options.

Working Principles

The TPS3898ADRYR operates by comparing the input voltage with a set threshold. If the voltage falls below or exceeds this threshold, the IC triggers a reset signal. Additionally, the power-on reset feature ensures a clean start-up, while the watchdog timer monitors system activity and resets the system if necessary.
