Functional Features

Voltage Monitoring

The TPS3824-30DBVR continuously monitors the supply voltage and generates a reset signal when the voltage falls below the programmed threshold.

Power-On Reset Delay

Upon power-up, the TPS3824-30DBVR introduces a fixed delay before generating the reset signal. This delay ensures that the system stabilizes before it starts functioning.

Manual Reset Input

The manual reset input allows for an external reset signal to be applied, overriding the voltage monitoring function.

Advantages and Disadvantages

Advantages

• Low-power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range allows for compatibility with various systems.
• Adjustable reset threshold provides flexibility in different voltage monitoring scenarios.
• Small package size enables space-saving designs.

Disadvantages

• Lack of built-in hysteresis may lead to potential issues in noisy environments.
• Limited number of pins restricts additional functionalities without external circuitry.

Working Principles

The TPS3824-30DBVR operates by comparing the supply voltage against the programmed threshold. When the voltage drops below this threshold, the internal circuitry triggers a reset signal, which can be used to restart or initialize the system.

Detailed Application Field Plans

The TPS3824-30DBVR finds applications in various fields, including: 1. Microcontroller-based systems 2. Industrial automation 3. Automotive electronics 4. Power management systems 5. Consumer electronics
