TPS389030DSET

The TPS389030DSET is a voltage supervisor integrated circuit (IC) manufactured by Texas Instruments. It is designed to monitor power supply voltages and provide a reset signal to microcontrollers and other digital devices when the supply voltage falls below a specified threshold. This ensures that the system operates reliably and prevents erratic behavior during power fluctuations.

Key Features:

1. Voltage Monitoring: The TPS389030DSET can monitor a range of supply voltages, typically from 0.5V to 5.5V, making it suitable for various applications, including battery-powered devices and systems with low-voltage logic.

2. Adjustable Reset Threshold: The reset threshold voltage can be set using external resistors, allowing designers to customize the reset point according to their specific application requirements.

3. Low Quiescent Current: The device is designed to operate with low power consumption, which is particularly beneficial in battery-operated applications where energy efficiency is critical.

4. Fast Reset Response: The TPS389030DSET features a fast reset response time, ensuring that the reset signal is generated quickly when the monitored voltage drops below the threshold, thus protecting the system from potential damage or malfunction.

5. Active-Low Reset Output: The reset output is active-low, meaning that it goes low when a reset condition is detected. This output can be directly connected to the reset pin of a microcontroller or other digital devices.

6. Temperature Range: The device operates over a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

7. Package Type: The TPS389030DSET is available in a compact package, such as a small-outline integrated circuit (SOIC) or a thin-shrink small-outline package (TSSOP), which is advantageous for space-constrained designs.

8. Additional Features: It may include features such as a manual reset input, watchdog timer functionality, and the ability to monitor multiple voltage rails, depending on the specific variant of the TPS389030 series.

Applications:

The TPS389030DSET is commonly used in various applications, including:

• Microcontroller and microprocessor reset circuits
• Power management systems
• Battery-operated devices
• Automotive electronics
• Industrial control systems
• Consumer electronics

Conclusion:

Overall, the TPS389030DSET from Texas Instruments is a versatile and reliable voltage supervisor that enhances the stability and reliability of electronic systems by ensuring proper reset functionality during power supply variations.
