Detailed Pin Configuration

The TPS389030DSER has three pins:

1. VDD: This pin is connected to the power supply voltage.
2. GND: This pin is connected to the ground.
3. RESET: This pin outputs a low signal when the monitored voltage falls below the threshold.

Functional Features

• Accurate voltage monitoring: The TPS389030DSER ensures precise monitoring of the voltage levels in electronic systems.
• Adjustable reset timeout: The reset timeout period can be adjusted to suit specific system requirements.
• Low quiescent current: With a typical quiescent current of 2.5µA, the TPS389030DSER minimizes power consumption.
• Active low output: The active low, push-pull output provides a reliable indication of voltage status.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring ensures system stability.
• Adjustable reset timeout allows customization.
• Low quiescent current reduces power consumption.
• Small package size enables use in space-constrained applications.

Disadvantages

• Limited voltage range (1.8V to 10V).
• Active low output may not be suitable for all applications.

Working Principles

The TPS389030DSER operates by comparing the input voltage with a fixed threshold voltage. When the input voltage falls below the threshold, the RESET pin outputs a low signal, indicating a voltage fault condition. The reset timeout period can be adjusted to determine how long the low signal is maintained after the voltage returns to normal.

Detailed Application Field Plans

The TPS389030DSER is commonly used in various electronic systems that require reliable voltage monitoring and supervision. Some potential application fields include:

1. Power supply units: Ensuring stable voltage levels in power supply units is crucial for the proper functioning of electronic devices.
2. Microcontrollers: Voltage monitoring is essential to prevent data corruption and ensure reliable operation of microcontrollers.
3. Industrial automation: In industrial settings, voltage supervision is necessary to maintain the integrity of control systems and prevent equipment damage.
4. Automotive electronics: Monitoring voltage levels in automotive electronics helps prevent malfunctions and ensures safe operation of vehicles.
